Limit to Shapefiles 1826 1
Started by Deleted User
A customer has posed the following question:
Error is Assertion failed!Programs:....File: shpopen.cLine 928Expression: psObject -> nSHPType==psSHP -> nShapeType ||psObject->nSHPType==SHPT_NULL
I am reading in shapefiles (they are large ssurgo soils for US states) and writing out a new shapefile with a subsample of the shapes,
the code works great for smaller states, but fails when there are say over ~1 million shapes. Is there a size limit and if so can you remove the size limit

Old program not working on new system 1939 1
Started by Deleted User
An IDL user has asked the following question:
I upgraded to 8.5 earlier this year (License ID: 5500131) as I am now running OS X Yosemite (10.10) and a data processing program I used previously not longer works. This is an old program (circa early 2000s) that reads binary data files from an older satellite and produces a save set of the data. When I use the program in the present idl version, the data it produces is garbage. It appears to be a problem with reading the binary file.

Hi, I'm brand new to IDL but I've been banging my head off this all day: I'm reading in a set of 55 structures from fits files and I'd like to consolidate them into a single structure that I can call without having to redo the read in every time. Unfortunately IDL's need to define everything prior to use has made it rather more difficult than other programs to do this.
The code below is roughly what I would like to do. (Although obviously it doesn't work like this)

Floating illegal operand with EXP and real numbers 2129 0

I have code running on two separate 64-bit Linux machines. One machine is running IDL v8.2 while the other is running v8.2.2 (these machines are owned by different entities, thus the different versions and licenses).
When I run my code on the v8.2.2 machine, however, I get "floating illegal operand" errors that I do not get on the v8.2 machine. Tracking this down reveals that the errors are created when using the "EXP" function with real numbers (as opposed to NaN values).
