Couldn't agree more Dan. How many post here do we see here saying "tried to get my horribly formatted piece of csv / excel / whatever" into ArcGIS and it didn't work, what can I do..." I am an old timer, I know, but one thing I always emphasise with beginners is data, data & data, know what it is & what it means. Especially the coordinates. ... View more

Couldn't you use some variant of the code posted here by Dan Patterson.. Calculate Distance. ... View more

Just did a quick test. Yes, the spatial join does correctly handle the underlying features. It counts them twice when summing into the larger overlapping polygons. ... View more

But, better do some tests here on how the spatial join handles the overlapping bits. Not sure if it will "count twice" these farms / fields in the overlapping portions. ... View more

Does this link offer any clues. See Mark Ireland's response. Obviously linking to extended data objects is not easy-peasy. Google Groups ... View more

Had a look at your data and spatially joined poly_area to buff_15 with the sum option. Took about 2mins. My version 10.3.1 on Win7 64bit. ... View more

Just zoomed into upper state NY in ArcMap. The online imagery basemap is using NAIP 1m 2013 imagery. At the very least you could see if it is suitable before acquiring your own. ... View more

Or, in the mxd, copy the layer several times and use a definition query on each one. ... View more

Note the left & right alignment between your 2 examples. In the OID column, the first is assumed text (left aligned), the 2nd is right aligned and is assumed to be numeric, then the text contents get dropped. I presume the 2 tools read a different number of rows to decide whether the field is numeric or text. ... View more

Sorry, not with you. In the route events layer, everything in both the original polyline and the route identifier should be there. If you now want to make this permanent, right click on the event layer and export into your db. ... View more

I don't think so. Done this many times. Are you sure that your route identifier field on both sides actually match? And I would still get rid of any spaces in the attribute names. ... View more

When you did the Display Route Events dialog did you specify to create a LOC_ERROR field? This will help you find those records in your table which did not match via your FEATURE_LA / Section Label route id field. And, if those are spaces in those field names, I would get rid of them. Spaces in field names can result in all sorts of strange things happening. ... View more

I very much doubt that the projection is being handled incorrectly. But what is your purpose for this? And I ma surprised that your output is still a circle with a particular radius. Depending on where it has been placed (high latitudes vs an equatorial location), I would expect that the Web Mercator version gets quished into some sort of ellipse in degrees. ... View more

4326 WGS84 is a geographic coordinate system based in degrees not metres. ... View more

In the layer properties / labels tab, there is a scale range setting button. Can't you use that? ... View more
