Learning About Remote Sensing

10/11/2011

As image processing software becomes more automated and therefore easier to use, I find myself talking to more people who have less formal education in remote sensing. It’s a great thing that this technology is becoming more accessible to more people. And yet, to get the most out of remotely sensed data, it can really help to... Read More >

Implicit Get/SetProperty calls in user-defined classes

10/6/2011

Operator overloading in user-defined classes was introduced in IDL 8 through the IDL_Object class. Mike Galloy explains how to use this technique here. One somewhat overlooked feature of IDL_Object is that it allows implicit calls to the GetProperty and SetProperty methods of a class. As a rule, member variables of an IDL class are protected,...

Getting to Know LiDAR

10/4/2011

I’ve worked with a lot of different types of geospatial data in my years at ITT VIS, but one type that I’ve had relatively little experience with is LiDAR. So, when ITT VIS announced that we would be releasing a new LiDAR application, E3De, I figured it was time to come up to speed. Here are a few things I’ve learned and... Read More >

Using IDL 8 Graphics (a.k.a. New Graphics)

9/29/2011

I’ve been using Direct Graphics (DG) in IDL since 1993. I was initially hesitant about IDL 8 Graphics (christened “New Graphics” on the comp.lang.idl-pvwave newsgroup; I’ll refer to them as NG), but I’ve been pleasantly surprised by how well they work. In particular, I like how their syntax mirrors DG and how... Read More >
