Summary
Tool/Script to produce any number of equal-size tiles from an existing raster dataset (raster/grid, TIFF, GIF, etc). Tiles can be resampled during creation. Buffer/overlap of tiles can be selected. Handy if you have preprocessed raster data that you want to break down into smaller bits for processing... Comes in a toolbox with dialog help. Dependencies: ------------- - ArcGIS 9.1 or older w/ Spatial Analyst needed. - Python 2.1+ (check http://support.esri.com/index.cfm?fa=knowledgebase.techarticles.articleShow&d=26872 for issues installing a newer Python version with ArcGIS) 'Installation': --------------- Unpack files tile.py + Tile.tbx into your favorite toolbox directory and add toolbox 'Tile' to your tools. Double click on Script 'Tile raster' in Toolbox 'Tile' and read documentation. History: -------- v0.32 some editing of documentation v0.31 workaround for decimal bug v0.3 use 'clip' function, correct extent to multiple of cellsize. v0.2 support tool dialog KnownBugs: ---------------- - Needs to be adapted to the new handling of Python in ArcGIS 9.2+ - Tiles don't align correctly at cell borders when cellsize precision needs more than 6 decimals. Use "Support small cellsize" option in this case - Extent and cellsize has to be set, 'Default' will not work. - Resampling doesn't always work ToDo: ----- - Bugfixes - Script to tile other input data... Feedback: --------- Bug reports greatly appreciated ;-)
