If you have got the vertices as points and their Z values. Why not summarise these (Analysis / Summary Statistics) using the RouteID as the case, and minZ, MaxZ as the statistics. Then join the resultant table back to your polyline routes. ... View more

On ArcGIS desktop you use the "Data Frame" toolbar to rotate the frame relative to the data. But you are probably talking about some programmatic way of doing this. ... View more

Also check for null geometries. A spatial select wouldn't find these. Maybe repair would work, but if these are in SDE, that might be a non-starter. ... View more

Yes, that extent looks pretty strange. I was going to post here the help on AddSpatialIndex_management etc here, but that seems to be what you are doing in your model anyway. Are you absolutely sure that your coordinate system is correct for this data or that there isn't a small piece of geometry out by the moon somewhere? ... View more

Ok, went to their web site and got the original pdf. Then printed it to a jpeg to have a play with the georeferencing. Tried a standard SAf albers, but the map is centred on ~21degE (instead of 24 or 25E). Georeffed it using points along the coast / border, but it also looks pretty horrible. The map has been put together in Coral Draw. So its very difficult to get this correct without knowing what the original is in. Could try contacting the author - Shaheed Russon (from the properties of the pdf). ... View more

As Luke said... The tfw file does not actually contain any information about what the actual coordinate system for the data is. For raster files it is just a reference for the corner coordinate and the cell size / rotation of the grid. This doesn't seem appropriate for LAS point files. If you still have access to the supplier, get them to tell you the exact parameters of the coord sys of the information. (projection system with its parameters and the datum on which it is based). ... View more

Is this data or a piece of paper? And the source? DMR?.. If its national extent it may be a SAf Albers equal area projection. Can you post a snapshot here? ... View more

I investigated the speed of deleting a large number of features recently. I found that both DeleteFeatures & a da.UpdateCursor / deleteRow managed about 50 records per second. So, even if you get it to work it will take a long time. Rather go Luis' route and not create the features you don't want in the first place. ... View more

I think that there is only the "generateToken" call to the server. You can also generate a token with a long expiry by specifying "expiration" : 1000 or something for a large number of seconds validity. Otherwise check the expires property against the system time as you suggest. ... View more

"exported as a shapefile", huh.... What was the original format of the data? Read up on editing in the help files. And also the advantages of keeping data in geodatabases. ... View more

Which map of SA is it? If you havn't got a graticule to use and you don't know what coordinate system the map has been published in, this will be quite difficult. ... View more
