In this exercise, you will work with the Quad_24K_NAD83.xml file, generating the grid features for the Austin East map document and modifying how the grid is displayed. General: INFO format: The INFO format is an ESRI native format that can be read and edited only by ArcGIS products. Grid lines and labels can be styled per grid level with setLineSymbol(gridLevel, lineSymbol) and setTextSymbol(gridLevel, textSymbol) methods on the grid. No. The grid, like a coverage, is stored as a separate directory with associated tables and files that contain specific information about the grid. Single file—extension *.asc. In addition, you can choose the output format for the raster dataset: BMP, ENVI, Esri BIL, Esri BIP, Esri BSQ, GIF, GRID, IMG, JPEG, JPEG 2000, PNG, TIFF, CRF, MRF, or exporting to a geodatabase. Reading the ArcGIS help: Supported raster dataset file formats, I read that ASCII Grid file types are addressed with the singular file extension .asc for both 16 bit signed-integer (for discrete data) and 32 bit floating-point files (for continuous data). INFO files should not be edited with other applications or removed with the operating system. ; Select the Labels component. A grid is a raster data storage format native to ESRI. ... ArcInfo GRID format does have an extension: .ADF, however like shapes and filegdb there is more than one file on disk for a single raster. No. Arc/INFO GRID format rasters are unique in their file structure. A workspace contains one info subdirectory and a subdirectory for each GRID. USNG allows the use of only two geographic coordinate systems: NAD 1983 (equivalent to WGS 1984) or NAD 1927. No. Select the custom grid in the Contents pane, right-click, and choose Properties. No. ; In the Format Map Grid pane, choose the layer in your map frame to base the grid on from the Layer drop-down list. 32-bit floating point. Read-only (Write—requires ArcGIS Spatial Analyst extension) 16-bit signed integer. In an integer grid directory (originally created by ArcInfo Workstation), the following tables and files are found: the BND table, which stores the boundary of the grid… For this exercise, you will modify an existing grid XML file and create new grids and graticules layers. ; Choose the field grid labels will be based on from the Field drop-down list. No. United States National Grid (USNG) The USNG coordinate notation format is a simplified version of MGRS based on the United States National Grid. No. The ArcGIS Desktop Advanced ASCII Grid format is an ArcGIS Desktop Advanced Grid exchange file. View supported formats. Each GRID subdirectory contains several files that store geographic location and attribute data for the corresponding grid. ; Switch to the Components tab in the Format Map Grid pane. A number of standard grid templates are included in ArcGIS Desktop. Each layer in a data frame references a data source. ASCII Grid. They say in ESRI Grid format section:. log file: The log file is an ASCII file that contains information about the creation of and alterations to a grid. When exporting your data to a file-based raster dataset using a clipping option, it is recommended that you enter a NoData value. For more information, see Standard for a United States National Grid, FGDC-STD-011-2001. GRID rasters are stored in workspaces.
