I'm not exactly sure where you're at with this, but are you aware of the Get Field Value tool? If you have a dataset with the FIPS code in the first row, you can collect it and use as an in-line variable for your output FC name. ... View more

Which tool exactly are you using (which toolbar is it on)? The Make Route Event Layer takes a route as input, but you only have a line. Have you tried Create Routes? ... View more

Not sure about deletion performance, but since you're at 10.3, you may want to use arcpy.da cursors which are much faster than old-school cursors. ... View more

Unfortunately, "thickly wooded area" automatically means that you're going to face additional challenges. I know they want to rely on GPS, but sometimes flagging is the best option. Some things you can try to improve your accuracy: - use GLONASS satellites, in addition to GPS (it looks like your unit does, but not sure if it does by default) - elevate the antenna As for the compass, you can get units with an internal electronic compass that does not require movement to work. ...

Summary Statistics, using AREA as case field and the other fields as statistics fields should do the trick. ... View more

You need two measurements: the scale bar at the bottom of the screen, and your distance away from the screen. For example, if I zoom in as far as it will let me go, the scale bar at the bottom reads from 0 to 1 m. I measure it with a ruler to determine that the scale bar is 2.55 cm long. Using math, I determine that this is equal to 0.000392156 km/cm. I measure my viewing distance as 100 cm from the screen. Using the formula from the blog post, I can calculate that the viewing distance is as if I were 0.0392156 km above the map, or 39.2 m. ... View more

I'm not sure I understand your problem. This is how I understand it: you are trying to run an interpolation tool like IDW. There is an optional parameter for cell size, in which you can select an existing raster to use its cell size. Since your output raster doesn't exist (yet), you can't select it. Can you please clarify what I'm missing here? ... View more

CRS = Coordinate Reference System. I just noticed that you're using ArcGIS Online, which I don't use. The process in ArcGIS Desktop would be to switch the CRS in the data frame properties, but I'm not sure how to do that in AGOL. ... View more

I've never worked with Mars data, but I suspect you need to change your data frame coordinate system to one of the Mars CRSes (e.g. Mars 2000 or Mars 1979), if you haven't done so already. These are both geographic, so they will report units of degrees. I do not see any projected CRS for Mars, at least not packaged by default in ArcGIS 10.2.2. ... View more

There are at least a few ways to do this. Zonal Statistics where zone is the size of the raster in question, with statistic type MAXIMUM, will return the maximum value in the raster. You could also convert to numpy array and find the maximum value in that array, if you want to incorporate Python. I wouldn't be surprised if there was function that reads from the raster statistics directly, but a quick search didn't reveal it to me. edit: the arcpy Raster object does contain a maximum property that you can read directly. edit 2: Get Raster Properties looks like the tool you're after. ...

There are more ideas here​. Check that you have access to the rasters, and that the rasters haven't moved since building the mosaic dataset. ... View more
