Light Detection and Ranging (LIDAR) is a remote sensing system used to collect topographic data. This technology is being used by the National Oceanic and Atmospheric Administration (NOAA) and NASA scientists to document topographic changes along shorelines.

We have had bad luck in referencing JPEG 2000 aerials (.jp2) into CAD using Map Data Connect (CAD creates an undetachable, unloadable string of .png files for each user that opens the drawing), but have found that if we bring in the .jp2 file using MAPIINSERT, everything seems to work just fine.

Joe,
I think you are getting two features of Map3D confused and mixed up. If the polygons are standard AutoCAD objects then you need to use the Data Source on the map explorer tab of the task pane to connect and link the xls file. Also you need some type of information attached to the polygons to use as a “key” field/index that corresponds with a field in the xls file unless you want to link the records manually. Look at the help files for this topic “Overview of Linking Database Records to Objects”

Dude ! That is so cool ! I will try to use this idea somewhere; it is great.
We are using Map 3D and ArcMap at my office. We have an initiative developing now to bring the GIS world into our skill set. We have a lot to learn.
I am struggling through Map 3D and the documentation that comes with it. Some of the ‘help’ is not really very helpful. Can you explain simply or point me to a good tutorial that can show the follow method:
1. we have a DWG file with a tight set of layers; one layer contains polygon rectangles to use as sample data for a cemetery.
2. We have an XLS file that contains property data like the owner, date of purchase, section, block, plot, etc.
3. How do I turn the sample data layer into a feature set with an attribute table.
4. How do I join the property data from the XLS file to this layer.
I have used ‘attach DWG’ to bring in that sample layer, and Data Connect to link the XLS. Now I’m stuck. the Help doesn’t seem to define how to link this since I need a data table on the sample plot layer first. It just seems to take for granted that you will have this data already there.
Sorry if this sounds like a rant; been banging my head on the desk for several weeks on this (off and on).

Thanks man,

Comment on Transparency of Images by anthony

Great post

I had this some problem with overlapping scaned images. I used ER Mapper to stitch the overlapping scans together in my case.

This option is a lot less time consuming and costly.

Nice one

Agree, there are many types of aerials the user needs to know just what the aerial is other than a picture from above. That’s where the meta-data comes into play unless the user knows the source of the image file.

there are many kinds of “aerial” images; it might be helpful to distinguish “sraight dowm” “aerial” photos that have been correlated with/corrected to control geometry by calling that class of images orthophotos:

http://en.wikipedia.org/wiki/Orthophoto

An orthophoto or orthophotograph is an aerial photograph geometrically corrected (“orthorectified”) such that the scale is uniform: the photo has the same lack of distortion as a map. Unlike an uncorrected aerial photograph, an orthophotograph can be used to measure true distances, because it is an accurate representation of the earth’s surface, having been adjusted for topographic relief[1], lens distortion, and camera tilt.

you’ve put a lot of effort into this, and it’s much appreciated. Made me think outside the box and gave me some ideas. Thanks!
