I want to run a urbanization model. Required data are;
- Classified raster data
- Slope etc.
I've downloaded DEM data from USGS Earth Explorer. Downloaded data are in DTED format. I use EPSG:32636 coordinate system in this project. All satellite imagery are in same coordinate system and pixel sizes are fixed 30m x 30m.(Landsat imagery)
Model wants all data projected into same coordinate system. DEM data was in GCS_WGS_1984 format, I have projected DEM data to EPSG:32636 in ArcGIS and setted output pixel size to 30 meters.
Then I've clipped the data so that it can fit study extent.
The Problem is; After clipping the data I've realized that; number of pixels are not same with the classified satellite imagery. In my slope tif file there are more pixels than the imagery.
They doesn't coincide ?
All satellite imagery pixels coincides but I couldn't understand why slope data doesn't coincides with the satellite image pixels.
PS: I've followed and tried the methods described in these web sites;
