ARIS ASCII Grid Reader for ArcGIS

The ASCII Grid Reader adds native support (direct read) for ESRI ASCII Grids to ArcMap and ArcCatalog, automatically stretching between MIN and MAX values in the GRID.

Spatial models which have been written outside of standard GIS applications (i.e. written in C/C++ or Fortran), often use the ASCII Grid format for storing intermediate and / or final results.

ARIS has a solution (already since ArcGIS 8) which makes it possible to preview ASCII Grids directly and without conversion in ArcCatalog, and to use them in ArcMap. All the usual raster operations in ArcMap (for example the Spatial Analyst tools in ArcToolbox) can then be applied to the ASCII Grid.

Floating-point and integer type ASCII Grids are recognized automatically.

When an ArcGIS projection file (.prj) is placed next to the ASCII grid with the same name but different extension (e.g. world.grd and world.prj), the projection information is passed automatically to ArcCatalog and ArcMap.

ARIS ASCII Grid Reader calculates automatically MIN and MAX values (statistics) in order to display the grid in the applicable range (The default ESRI *.ASC reader in ArcGIS 9.3/9.3.1/10.0 does not calculate those values and shows an all grey or black GRID).

ARIS ASCII Grid Reader recognizes the following file extensions:

• .agr
• .aig
• .asc
• .grd

New features
A Floating License is introduced next to the existing Single Use license (Unrelated to your ArcGIS license form).
The ARIS ASCII Grid Reader for ArcMap 10 has some exciting features to support also some non-ESRI ASCII Grids:

• Non-square/rectangular cell size by using keywords XCELLSIZE and YCELLSIZE
• Non-square/rectangular cell size by using keywords XDIM and YDIM
• Non-numeric Nodata value like "NULL", "NA", "mv", "!", "-"
• Any order of the keywords in the header

Requirements
Required is one of the following ArcGIS 8, ArcGIS 9.2, ArcGIS 9.3, ArcGIS 9.3.1, ArcGIS 10.0, ArcGIS 10.1, ArcGIS 10.2/10.2.1/10.2.2, ArcGIS 10.3/10.3.1 or ArcGIS 10.4 / 10.4.1 licenses:

• ArcView / ArcGIS Desktop Basic
• ArcEditor / ArcGIS Desktop Standard
• ArcInfo / ArcGIS Desktop Advanced

The Spatial Analyst extension or Data Interoperability extension is not required.
