As a consequence, the identified format can only constitute a "best guess" and must always be considered as tentative and subject to revision, as more is learned. It appears that all ARC/INFO files except user-created lookup tables are exported, including .ACODE and .PCODE. 2 OVERALL ORGANIZATION The export file begins with a line with three fields. 1- an initial 'EXP' 2- what appears to be a constant of '0' 3- the pathname for the creation of the export file The export file ends with a line beginning 'EOS'. The ARC files are included first, in alphabetical order except for the SIN, LOG, and PRJ files which occur last. Then the INFO files are included in alphabetical order. The beginning of each ARC file is indicated by the file name (a three-character identifier) followed by ' 2' for single- precision or ' 3' for double-precision. Single-precision carries 8 digits, and double-precision carries 15 digits. Each ARC file ends with a line of seven numbers beginning with a -1 and followed by six zeros, except the SIN, LOG, and PRJ files which end in 'EOX', 'EOL', and 'EOP', respectively. The LAB file uses a slight variation of this -1 ending line (see below). The format for each ARC file is specific to that type of file. These formats are covered below. The beginning of the INFO file section is indicated by 'IFO 2', and its end is indicated by 'EOI'. The INFO files each begin with the file name. For example, the polygon attribute table would be 'STDFIG24C.PAT' on a line by itself. The format is the same for every INFO file. This format is given below. 3 ARC FILE FORMATS Formats will be given for the most common ARC files: ARC CNT LAB LOG PAL PAR PRJ SIN TOL 3.1 ARC The ARC (arc coordinates and topology) file consists of repeating sets of arc information. The first line of each set has seven numbers: 1. coverage# 2. coverage-ID 3. from node 4. to node 5. left polygon 6. right polygon 7. number of coordinates The subsequent lines of a set are the coordinates with two x-y pairs per line, if the coverage is single-precision. If there are an odd number of coordinates, the last line will have only one x-y pair. Double-precision puts one coordinate pair on each line. An example of an actual ARC section follows: ARC 2 1 2 2 1 1 2 2 3.4029994E+05 4.1001998E+06 3.4009988E+05 4.1002000E+06 2 3 3 2 3 2 2 3.4050000E+05 4.1001998E+06 3.4029994E+05 4.1001998E+06 3 1 1 4 1 2 4 3.4009988E+05 4.1002000E+06 3.4040006E+05 4.1003995E+06 3.4090012E+05 4.1002000E+06 3.4070003E+05 4.1001995E+06 4 4 4 3 4 2 2 3.4070003E+05 4.1001995E+06 3.4050000E+05 4.1001998E+06 5 6 3 4 4 3 3 3.4050000E+05 4.1001998E+06 3.4059997E+05 4.1001002E+06 3.4070003E+05 4.1001995E+06 6 7 4 5 1 3 3 3.4070003E+05 4.1001995E+06 3.4079997E+05 4.1000002E+06 3.4019978E+05 4.1000000E+06 7 5 5 2 1 3 2 3.4019978E+05 4.1000000E+06 3.4029994E+05 4.1001998E+06 -1 0 0 0 0 0 0 An example of a double-precision ARC section follows: ARC 3 1 0 0 0 0 0 7 3.40200000000000E+05 4.10000000000000E+06 3.40300000000000E+05 4.10020000000000E+06 3.40500000000000E+05 4.10020000000000E+06 3.40600000000000E+05 4.10010000000000E+06 3.40700000000000E+05 4.10020000000000E+06 3.40800000000000E+05 4.10000000000000E+06 3.40200000000000E+05 4.10000000000000E+06 2 0 0 0 0 0 4 3.40100000000000E+05 4.10020000000000E+06 3.40400000000000E+05 4.10040000000000E+06 3.40900000000000E+05 4.10020000000000E+06 3.40100000000000E+05 4.10020000000000E+06 -1 0 0 0 0 0 0 3.2 CNT The CNT (Polygon Centroid Coordinates) file contains the centroid of each polygon in the coverage. It has sets of centroid information with an initial coordinate line and, if there are labels, one line per label giving the number for the label. The coordinate line has three fields: 1- number of labels in polygon 2- centroid x 3- centroid y An example of an actual CNT section follows: CNT 2 0 3.4048516E+05 4.1001702E+06 1 3.4046691E+05 4.1002662E+06 1 1 3.4048875E+05 4.1000852E+06 2 0 3.4060000E+05 4.1001665E+06 -1 0 0 0 0 0 0 3.3 LAB The LAB (label point coordinates and topology) file consists of repeating sets of label point information. The first line of each set has four numbers: 1. coverage-ID 2. polygon which encloses it 3. x coordinate 4. y coordinate The second and final line of the set gives the label box window. This information is marked as marked as obsolete in the SDL documentation. It currently contains repetitions of the x and y coordinates. Note that the LAB section ends with a different '-1' line than the other files. An example of an actual LAB section follows: LAB 2 1 2 3.4046650E+05 4.1002668E+06 3.4046650E+05 4.1002668E+06 3.4046650E+05 4.1002668E+06 2 3 3.4048869E+05 4.1000852E+06 3.4048869E+05 4.1000852E+06 3.4048869E+05 4.1000852E+06 -1 0 0.0000000E+00 0.0000000E+00 An example of a double-precision LAB section follows: LAB 3 1 2 3.40500000000000E+05 4.10006225000000E+06 3.40500000000000E+05 4.10006225000000E+06 3.40500000000000E+05 4.10006225000000E+06 2 3 3.40468812500000E+05 4.10026225000000E+06 3.40468812500000E+05 4.10026225000000E+06 3.40468812500000E+05 4.10026225000000E+06 -1 0 0.00000000000000E+00 0.00000000000000E+00 3.4 LOG The LOG (Coverage History) file contains a free form set of lines of indeterminate number which are separated by lines which begins with a tilde, "~". ARC records many commands and their resource impacts in this file. The standard ARC format for writing in the LOG has nine fields: Year (I4) Month (I2) Day (I2) Hours (I2) Minutes (I2) Connect Time in minutes (I4) CPU Time in seconds (I6) I/O Time in seconds (I6) Command line (A100) However, any information can be added to the LOG file in free- form format. An example of an actual LOG section follows: LOG 2 19940118 849 0 3 35export cover landli stdfigc none ~ 19940118 850 0 7 190clean landli landlicp # # poly ~ EOL 3.5 PAL The PAL (Polygon Topology) file consists of repeating sets of polygon information. The first line of each set has five numbers: 1. number of arcs in polygon 2. x min of polygon 3. y min of polygon 4. x max of polygon 5. y max of polygon The subsequent lines of a set give information on the arcs which comprise the polygon. There are three numbers per arc with information for two arcs per line. 1. the arc number (negative if reversed) 2. the node number 3. the polygon number The first polygon given is the universal polygon. "The PAL file contains the polygon topology for a coverage and min-max boxes for the polygons. For each polygon in a coverage the PAL file has a (usually) clockwise list of the arcs, nodes that comprise the polygons, as well as the adjacent polygons, and a min-max box. To keep a continuous list, 'virtual' arcs with arc# of 0 are used to connect to holes (thus forming donuts), which are connected in counter-clockwise order. The PAL file is a random access, variable record length file, with the length dependent on the number of arcs surrounding the polygon (1 to 10000). The arc# in the PAL file is the record number of that arc within the coverage's ARC file, the node# is the same as the node# in the arc file at the appropriate end, and the polygon# is the record number of that polygon within the coverage's PAL file. The PAL file record number for a polygon is the same as the PAT file record number and the CNT file record number." SDL documentation, July 1989, p. 24. An example of an actual PAL section follows: PAL 2 5 3.4009988E+05 4.1000000E+06 3.4090012E+05 4.1003995E+06 0 0 0 -1 1 2 -7 2 3 -6 5 3 -3 4 2 4 3.4009988E+05 4.1001995E+06 3.4090012E+05 4.1003995E+06 1 2 1 3 1 1 4 4 4 2 3 3 4 3.4019978E+05 4.1000000E+06 3.4079997E+05 4.1001998E+06 -2 2 2 5 3 4 6 4 1 7 5 1 2 3.4050000E+05 4.1001002E+06 3.4070003E+05 4.1001998E+06 -4 3 2 -5 4 3 -1 0 0 0 0 0 0 3.6 PRJ The PRJ (Projection Parameters) file consists of a set of projection keywords and values including a set of parameters following the keyword "Parameters". This file needs further research for specific keywords and parameters for the projections supported by ADS and MOSS. An example of an actual PRJ section follows: PRJ 2 Projection UTM ~ Zone 13 ~ Datum NAD27 ~ Zunits NO ~ Units METERS ~ Spheroid CLARKE1866 ~ Xshift 0.0000000000 ~ Yshift 0.0000000000 ~ Parameters ~ EOP 3.7 SIN Spatial Index It usually is comprised of a single line with the value "EOX". An example of an actual SIN section follows: SIN 2 EOX 3.8 TOL This consists of ten lines with a tolerance type, a tolerance status, and a tolerance value on each line. The tolerance types are: 1. fuzzy 2. generalize (unused) 3. node match (unused) 4. dangle 5. tic match 6. undefined 7. undefined 8. undefined 9. undefined 10. undefined The tolerance status "is set to 1 if the tolerance is verified (been applied to operations of the coverage) and to 2 if the tolerance is not verified (been set by the TOLERANCE command, but not yet used in processing)." An example of an actual TOL section follows: TOL 2 1 1 8.1813842E-01 2 2 0.0000000E+00 3 2 0.0000000E+00 4 1 0.0000000E+00 5 2 0.0000000E+00 6 2 8.0025000E+00 7 2 8.0025000E-01 8 2 8.0025000E-01 9 2 8.0025000E-01 10 2 8.0025000E-01 -1 0 0 0 0 0 0 An example of a double-precision TOL section follows: TOL 3 1 2 8.00000000000000E-02 2 2 0.00000000000000E+00 3 2 0.00000000000000E+00 4 2 0.00000000000000E+00 5 2 0.00000000000000E+00 6 2 8.00000000000000E+00 7 2 8.00000000000000E-01 8 2 8.00000000000000E-01 9 2 8.00000000000000E-01 10 2 8.00000000000000E-01 -1 0 0 0 0 0 0 4 INFO FILE FORMATS INFO files follow the same format: name of the info file and summary information definitions for each of the items actual data values The name line consists of six fields: 1. name of the INFO file 2. appears to be flag for ARC/INFO table ('XX') or other INFO table (' ') 3. number of items 4. appears to repeat number of items 5. length of data record 6. number of data records The definitions for each item consist of eight fields: 1- name of item 2- width of item followed by a constant of '-1' 3- start position of item followed by a constant of '4-1' 4- output format of item (see below for discussion) 5- type of item (see below for discussion) 6- appears to be constant of '-1' 7- appears to be constant of '-1-1' 8- appears to be sequential identifier The output format field is handled differently for numeric and character items. Numeric items give the output width followed by a space then the number of decimal positions. Character items give the output width followed by a constant of '-1'. The type of the item is specified by the following codes: 20-1 indicates character 50-1 indicates binary integer 60-1 indicates real number The other item types have not yet been identified. Formats will be given for the most common INFO files: .AAT .ACODE .BND .PAT .PCODE .TIC 4.1 .AAT The .AAT (Arc Attribute Table) contains seven fields whose item names are self-explanatory. However, additional items may be added as desired, after the -ID item.

The remaining areas of uncertainty include: confirmation of the meaning of the second field in the identification line for INFO files ('XX' or ' ') the meaning of the 'SIN 2' section the precise format of the PRJ file for different projections possible variation in the '-1' suffixes of INFO definitions INFO codes for item types other than character, integer, and real. However, none of these appears to be that serious, and the indicated formats should be used to identify any errors or limitations. Because this information was derived from limited experimentation, it should be considered as tentative and subject to revision at any time.

As a consequence, the identified format can only constitute a "best guess" and must always be considered as tentative and subject to revision, as more is learned. This document is a supplement to the information in Analysis of ARC EXPORT File Format for ARC/INFO (Rev 6.1.1). GRID files usually occur in separate export files, although they follow the standard export format. 2 OVERALL ORGANIZATION The GRID export file begins with a line with three fields. 1- an initial 'EXP' 2- what appears to be a constant of '0' 3- the pathname for the creation of the export file The export file ends with a line beginning 'EOS'. The ARC files are included first, with the GRD file first, followed by the LOG and PRJ files, if they exist. Then the INFO files are included in alphabetical order. The beginning of each ARC file is indicated by the file name (a three-character identifier) followed by ' 2' for single- precision. Floating-point GRID files appear to be always single- precision. They are unaffected by the ARC PRECISION command, and the precision-related keyword for the ARC COPY command is ignored. Single-precision carries 8 digits. Integer GRID data is given as integers in the EXPORT file. Each ARC file ends with a special identifier line: 'EOG' for the end of the GRD file section, 'EOL' for the end of the LOG file section, and 'EOP' for the end of the PRJ file section. The beginning of the INFO file section is indicated by 'IFO 2', and its end is indicated by 'EOI'. The INFO files each begin with the file name. The format is the same for every INFO file. This format is given in Analysis of ARC EXPORT File Format for ARC/INFO (Rev 6.1.1). 3 ARC FILE FORMATS The format will be given for the GRD file. The formats for the LOG file and the PRJ file is given in Analysis of ARC EXPORT File Format for ARC/INFO (Rev 6.1.1). 3.1 GRD The GRD file is a composite of information from several ARC files: BND, HDR, Q0X1Y1, and Q0X1Y1X. It consists of four sections: dimensions, cell size, MBR, and cell values. The dimensions section consists of one line with four numbers: 1. an integer number of columns 2. an integer number of rows 3. an integer type of GRID map 4. a double-precision floating-point number of unknown use (possibly the smallest signed integer ) The type of GRID map appears to be '1' for integer and '2' for floating-point. The cell size section consists of one line with two numbers: 1. cell height 2. cell width It has not been determined whether height or width actually comes first. The MBR section consists of two lines with two double-precison floating-point numbers per line: line 1, number 1 minimum x line 1, number 2 minimum y line 2, number 1 maximum x line 2, number 2 maximum y The cell value section contains a set of lines with the cell value data. Five cell values are given on each line. Each row begins on a new line. Therefore, if the number of columns is not a multiple of five, the remainder is placed on a line of its own. The next row does not begin until the next line. The extra number positions on the last line of the row may be either spaces or numbers. In either case, they are ignored. An example of an integer GRD file section follows: GRD 2 18 4 1-0.21474836470000E+10 0.30000000000000E+02 0.30000000000000E+02 0.37892300000000E+06 0.40723450000000E+07 0.37946300000000E+06 0.40724650000000E+07 5 3 2 4 6 1 1 1 1 1 2 2 2 2 2 5 2 3 3 2 1 3 5 3 3 3 3 3 4 4 4 4 4 3 3 4 1 1 1 4 1 5 5 5 5 5 6 6 6 6 6 1 3 1 2 3 5 6 2 7 7 7 7 7 8 8 8 8 8 3 2 4 EOG An example of a floating-point GRD file section follows: GRD 2 18 4 2-0.34028234663853E+39 0.30000000000000E+02 0.30000000000000E+02 0.37892300000000E+06 0.40723450000000E+07 0.37946300000000E+06 0.40724650000000E+07 0.5100000E+01 0.3200000E+01 0.2300000E+01 0.4500000E+01 0.6300000E+01 0.1000000E+01 0.1000000E+01 0.1000000E+01 0.1000000E+01 0.1000000E+01 0.2000000E+01 0.2000000E+01 0.2000000E+01 0.2000000E+01 0.2000000E+01 0.5400000E+01 0.2600000E+01 0.3300000E+01 0.3100000E+01 0.2400000E+01 0.1600000E+01 0.3500000E+01 0.5300000E+01 0.3000000E+01 0.3000000E+01 0.3000000E+01 0.3000000E+01 0.3000000E+01 0.4000000E+01 0.4000000E+01 0.4000000E+01 0.4000000E+01 0.4000000E+01 0.3500000E+01 0.3400000E+01 0.4700000E+01 0.1700000E+01 0.1700000E+01 0.1700000E+01 0.4300000E+01 0.1700000E+01 0.5000000E+01 0.5000000E+01 0.5000000E+01 0.5000000E+01 0.5000000E+01 0.6000000E+01 0.6000000E+01 0.6000000E+01 0.6000000E+01 0.6000000E+01 0.1700000E+01 0.3800000E+01 0.1700000E+01 0.2500000E+01 0.3300000E+01 0.5100000E+01 0.6200000E+01 0.2400000E+01 0.7000000E+01 0.7000000E+01 0.7000000E+01 0.7000000E+01 0.7000000E+01 0.8000000E+01 0.8000000E+01 0.8000000E+01 0.8000000E+01 0.8000000E+01 0.3900000E+01 0.2400000E+01 0.4100000E+01 EOG 4 INFO FILE FORMATS The INFO files each begin with the file name. The format is the same for every INFO file. This format is given in Analysis of ARC EXPORT File Format for ARC/INFO (Rev 6.1.1). Formats will be given for the following INFO files: .STA .VAT 4.1 .STA "The STA table is an INFO table that contains statistical data about a grid. The minimum, maximum, mean and standard deviation for the grid are stored as floating-point values in the STA table." Cell-based Modeling with GRID, Environmental Systems Research Institute, Inc., July 1991, p. A-3. An example of an .STA section follows: TEST5.STA XX 4 4 16 1 MIN 4-1 14-1 10 3 60-1 -1 -1-1 1- MAX 4-1 54-1 10 3 60-1 -1 -1-1 2- MEAN 4-1 94-1 10 3 60-1 -1 -1-1 3- STDV 4-1 134-1 10 3 60-1 -1 -1-1 4- 1.0000000E+00 8.0000000E+00 3.8055556E+00 2.1254992E+00 4.2 .VAT "The VAT is an INFO table that stores attributes associated with the zones of a grid. Only integer grids have a VAT assocaited with them. Every VAT has at least two items, VALUE and COUNT. The VALUE item contains integer values that are used to distinguish the characteristics of one location from other locations in a grid. All cells that are assigned the same value contain the same characteristics, and, therefore, belong to the same zone. COUNT is the number of cells in a zone." Cell-based Modeling with GRID, Environmental Systems Research Institute, Inc., July 1991, p. A-3. An example of a .VAT section follows: TEST5.VAT XX 2 2 8 8 VALUE 4-1 14-1 10-1 50-1 -1 -1-1 1I COUNT 4-1 54-1 10-1 50-1 -1 -1-1 2- 1 12 2 11 3 14 4 9 5 9 6 7 7 5 8 5 5 CONCLUSION The content and format of the ARC GRID EXPORT file seems to be straightforward. The remaining areas of uncertainty include: the meaning of the fourth field of the dimension line in the GRD section the order of the cell width and cell height in the cell size line of the GRD section However, neither of these appears to be that serious, and the indicated formats should be used to identify any errors or limitations. Because this information was derived from limited experimentation, it should be considered as tentative and subject to revision at any time.

Format of the ESRI Plot File. . . . . . . . . . 3 1 INTRODUCTION Note: ESRI considers the export/import file format to be proprietary. As a consequence, the identified format can only constitute a "best guess" and must always be considered as tentative and subject to revision, as more is learned. This document is a supplement to the information in Analysis of ARC EXPORT File Format for ARC/INFO (Rev 6.1.1). Plotfiles occur in separate export files, although they follow the standard export format. 2 OVERALL ORGANIZATION The plot export file begins with a line with three fields. 1- an initial 'EXP' 2- what appears to be a constant of '0' 3- the pathname for the creation of the export file The export file ends with a line beginning 'EOS'. There is only the PLT file section in a plot export file. The PLT file section begins with an identifier line 'PLT 2'. Although the '2' designates it as single-precision, it carries only 6 digits, instead of the 8 digits carried in other export sections. The PLT file section ends with an identifier line of 'EOP'. 3 PLT SECTION FORMAT The PLT (1039 plot) file consists of a series of plotter commands. These commands are simply reformatted and placed in the export file. These commands and examples are given in ESRI'S plot manual. The colors use the tektronics numbering system (e.g., red is 2, green is 3, etc.). An example of an actual PLT section follows: EXP 0 /HOME/PLOTS/STDFIG11C/STD1039A.E00 PLT 2 8 0.00000E+00 6.09794E+01 9 0.00000E+00 3.18962E+01 6 0.00000E+00 0.00000E+00 7 1.00000E+00 1.00000E+00 1 0.00000E+00 0.00000E+00 0 2 1 2.90378E+00 1.74181E+01 2 1.74227E+01 1.74000E+01 1 1.74227E+01 1.74000E+01 2 1.01542E+01 2.90378E+00 1 1.01542E+01 2.90378E+00 2 5.37109E+01 2.92192E+00 2 4.64582E+01 1.73819E+01 1 4.64582E+01 1.73819E+01 2 6.09794E+01 1.74181E+01 2 2.46889E+01 3.18962E+01 2 2.90378E+00 1.74181E+01 1 4.64582E+01 1.73819E+01 2 3.19416E+01 1.74000E+01 1 3.19416E+01 1.74000E+01 2 1.74227E+01 1.74000E+01 1 3.19416E+01 1.74000E+01 2 3.91965E+01 1.01791E+01 2 4.64582E+01 1.73819E+01 0 3 4 7.00000E-02 0.00000E+00 1 2.84025E+01 2.07491E+01 -5LARGE 1 3.17755E+01 6.52159E+00 -5SMALL 1 3.90442E+01 1.62341E+01 -5LARGE 0 4 1 1.00000E+00 1.00000E+00 -81039 TEX -1T 1 0.00000E+00 0.00000E+00 5 0.00000E+00 0.00000E+00 EOP EOS 4 CONCLUSION The content and format of the ARC EXPORT PLT section seems to be largely straightforward. However, because this information was derived from limited experimentation, it should be considered as tentative and subject to revision at any time.
