High Resolution Imagery from National Map |

![]() |
General directions for National Map. National Map imagery available for Annapolis. Be careful about the size of the region you request since these files can rapidly grow to huge sizes.
Some of these data sets are in WGS_1984_Web_Mercator_Auxiliary_Sphere projection. You can verify this by looking in the Geotiff File Metadata for the Geotiff created by GDAL. If the program does not automatically correct this, you must warp the image to usable UTM coordinates, on the Resample menu. If you need to merge tiles, get ready for the command line using GDAL. MICRODEM should hide the messy details. Do any merges before you warp. |
