You don't say what sort of db you are using here. In sde the geometry function is ST_Intersect (I think). This can return a query result, you would have to insert it into another feature, then calculate the area of that piece if geometry, as Wes says. Otherwsie just use the Intersect tool, which creates that other feature as part of its output. ... View more

And what errors are you getting? Have you imported the datetime module? ... View more

Rebecca, in those geometry methods, outContour would have to be a geometry object, not an entire feature class. I would load those 2 sets of geometries into a dict or something then get the logic right of cycling through them. ... View more

Yes, there have been other post here about the speed improvements once a task is coded using arcpy / python. Good to see you have your solution. ... View more

I normally do more complex stuff like this in python. So, could you show us your code? ... View more

Without knowing the details it is difficult to say. Type of db? Are you saying that the points are participating in a network? You may have to wrap the update cursor loop in an editor session. ... View more

Do you want to include "driving times" when on the road network? The roads could also be rasterized with some functions to output a "time in each cell" depending on road type. With all other cells as no data. Then develop the hicking function on the same scale (time across each cell). Then combine these together as suggested here : Conbining rasters with con/isnull ...

Why would you want to create features with an unknown spatial reference? ... View more

But it is always better to define the coordinate system when creating geometry. ... View more

No it doesn't. The unique field (Line field) specifies a separation between lines. The sort field specifies the order in which the points should be. If you have only 1 line, leave out the unique id. If the order of your points as they appear in the table is different from the actual connection order, use the sort field. ... View more

And to underline the point... You cannot actually see a *.las dataset directly, they have to be loaded into a *.lasd dataset, created in ArcCatalog first. And statistics should be done. ... View more

As regards jpg vs geotiff... I have some experience publishing ecw, which, apparently, you need a license for if you publish it. So we converted the imagery to tiff. If jpg is what you have, use it. As long as the final result looks good, go for it. ... View more

Yes, Mosaic datasets are best at welding together the imagery in whatever format the imagery is supplied in. There is no need to import them into a different format (fgdb, sde, whatever) before hand. Thus saving all those extra copies of stuff that can be quite big. They still have to be available to the service somewhere after publishing, unless you go the route of caching, which can be bigger than the original. ... View more
