One way would be using a raster GIS add on for MapInfo, like Vertical Mapper (VM). Then convert your contour lines to contour point (menu in VM), interpolation the contour point to a grid and making a point inspection on your points. This properly world give the most accurate result.
In the vector world you could find the nearest contour line to a given point, and update the point with the contour data, but this would not be as accurate as the raster way. If you work a lot with elevation data you should get a raster add on for MapInfo like Vertical Mapper or Engage3D HTH, Jakob Lanstorp Software Consultant Geographical Information & IT COWI A/S Odensevej 95 DK-5260 Odense S Tel +45 6311 4900 Fax +45 6311 4949 Mob +45 5050 8087 E-mail [EMAIL PROTECTED] http://www.cowi.dk http://www.cowi.com -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Sarah Chisholm Sent: Thursday, December 08, 2005 2:37 PM To: [email protected] Subject: [MI-L] point elevation data Hi all, Please forgive an extremely inexperienced MapInfo user with a deadline for this question. I am trying to figure out the easiest and quickest way to get the elevations of a series of points. I've got a contour line layer, and the points are plotted on the map, but I can't figure out how to pull out the elevation of each point. I'd love to figure out a query resulting in a table with the point coordinates and their corresponding elevations. Anyone who has a bit of time to help me would be my hero.
