I want to use python libraries to do image processing for very large files (over 2GB), but the current python libraries can not read 16 or 32 bit image correctly. At least, I tried Python Image library, GDAL etc. which gave me 8 bit images or 2/3 correct images. I want to try ArcGIS as the...

I have a number of drawings which I converted into geodatabase feature classes. Most drawings are composed or connected 3D polylines from which I want to construct TIN surfaces and multipatch features. In order to clip the TIN I also need to have the exact footprint. How I normally do it is...

First, I would like to highlight that QWC seems to be a fantastic tool. However documentation could be improved. I have installed from git with the install.sh script and went directly to copy a QIS project in the project directory (with map layers in Postgis). After struggling with CRS (in the...

I have a pdf showing a street map that also shows land use zoning as well. I need to digitise it on ArcMap to show all of the different streets and land use zones. I'm not too sure how to best go about this, the only way I know is to manually draw all the features again which would take a very...

I have built a web gis application using ExtJS 4 and GeoEext. I have a panel on the right side of the application in which I appear images based on a date filter. For this I have a vertical scroll bar as it can be seen in the first picture. The problem is that when I am using my application in...

I have a task where I have plotted positions along an alignment (see red dots in images) and I need to plot two offset points (from the chainage locations) at varying distance parallel to the alignment (see image 2). I am not sure how to go about it. I have thought about: working out the...

I have a pdf of a street map which is many different colors depending on land use, I need to import it into ArcMap and then digitize it. Obviously I could manually create each feature but that would take days. I've done some reading and it appears that I can use the ArcScan method to...

I am new to RF and EnMap. As a start, I followed the RF tutorial provided by EnMAP. My goal is to use RF to classify Landsat images using more than 100 explanatory variables. In the EnMap tutorial, it only says "input image." But what image? Is this the resulting image after stacking all the...

In ArcMap it is easy to include commas as thousands separators on a measured grid, as can be seen in the screenshot below, but I have not been able to find a way to change the separator used from being a comma to a space instead. There does not seem to be an Advanced ArcMap Setting to do it...
