  2. A global land cover GeoTIFF was recently released by Impact Observatory (IO) and Esri. To create this geospatial layer, hundreds of thousands of satellite photos were classified into ten unique land use/land cover (LULC) classes using a deep learning model in partnership with Microsoft AI for Earth. Sentinel-2 imagery was used to divide the world into ten categories of land use cover: Water (areas that are predominately water such as rivers ponds, lakes, and ocean) Trees (clusters that are at least 10 meters high) Grasslands such as open savannas, parks, and golf courses

  3. there is also a new tool in arcgis pro called "Pixel Editor" if you need to correct the values for this tool you need the Image analyst license. https://pro.arcgis.com/en/pro-app/help/analysis/image-analyst/editing-elevation-pixels.htm depending on your task or your licence you can also use the "Raster Calculator" (needs spatial analysis). For example if you have a polygon with the elevation data and you want to substitute the values on your raster (polygon to raster, then use the conditional function > con() https://desktop.arcgis.com/en/arcmap/10.3/tools/spatial-analy

  4. hi, why do you use landsat 7 and not landsat 8? and with witch software? here you can see the band combination for landsat 7 and 8 http://landsat.usgs.gov/L8_band_combos.php http://web.pdx.edu/~emch/ip1/bandcombinations.html so the band combination for TM is 1-4-7 in Landsat 7, the combination can be 7-6-4 http://www.harrisgeospatial.com/company/pressroom/blogs/tabid/836/artmid/2928/articleid/14305/the-many-band-combinations-of-landsat-8.aspx you load every single band in ArcGIS and you do a combination then do a classification (supervised or unsupervised)
