![]() ![]() ![]() If you restore that, Idrisi raster datasets cannot be display in ArcGIS once closed. It will be included in Idrisi version 18. We tested GDAL with revised Idrisi driver, all known bugs have been fixed. This works well, and insures the minimum changes on the original code although it is not necessary for READONLY. Considering only in another situation, Open() with READONLY mode, min/max will remain untouched, I removed "if condition" in destructor to allow min/max always computed. This causes the 0 min/max error.Ĭompute min/max values when the two situations happen. ![]() Instead, they just pass 0 to SetStatistics() in the destructor. But in the old code the band's dfMinimum and dfMaximum don't hold the values they are supposed to hold. The original purpose of this kind of design was good because client doesn't need to take care of writing min/max explicitly when calling GDAL. Setting min/max values was implemented in SetStatistics(), and was triggered in destructor when Ivan wrote the driver. After Open() with UPDATE access mode, need to modify min/max values to avoid error min/max caused by potential changes of pixel values.After a new RST dataset is created by Create() or CreateCopy() because min/max values in newly created RDC file are default 0 then.Min/max values need to be set in RDC file when two situations happen: Let me answer the question why re-compute min/max in destructor? With more than three decades leading the development of tools for the GIS analysis and the processing of satellite images (IDRISI), Clark Labs incorporates in this new version functionalities to add the temporal variable, creating what we can call a GeoTemporal System (GTS). ![]() TerrSet is an integrated constellation of applications for the monitoring and modeling of terrestrial systems, and offers innovative tools to intelligently address the main challenges of global growth: climate change, changes in land uses, ecosystem variations. TerrSet is the new software developed by Clark Labs in close cooperation with various institutions for sustainable development and environmental conservation. ![]()
