Update the voice and tense of the methods to agree #538

Closed mwernimont closed 4 years ago

(digitization reads as instructions, gage count reads as past tense method)

Assuming someone will create more harmonious text for all the methods, this ticket is to update that said text in the methods component text json file.

Updated text:

Historic urban extents were digitized using an ArcToolbox tool, "PDF to TIFF Conversion Tool". Each separate page of the provided PDF was converted into a geotiff format "TIF file" that was imported as a raster layer into ArcMap 10.7. After adding the TIF file into the current GIS project, the Georeferencing tool "Fit to Display" was used to pull the raster into the area of interest. Control points were identified and laid down to tie the non-geospatial TIF image to actual locations on the ground using the Georeferencing tool "Add Control Points". This stretched the raster into the current GIS projection, which is set at EPSG:3857. After successfully aligning the TIF to the geospatial extent of interest, a new empty shapefile was created. The Create Features toolset was used to manually trace polygons over the urban areas depicted in the original PDF.
