Re: MI Speeding up mapbasic code

Gentlemen and ladies, I am not sure if this will help but I have done some minor work in IDRISI and if you can avoid the 'temp' table creation and write to a user definable named table(s) do it. Simply use enough table names to allow for the kind of operation you are doing, e.g. - if you have to

RE: MI creating points from centroids

Sidney, This is a one step process using the MapBasic Window: 1. First make a copy of your table 2. Open the MapBasic window (Options > Show Mapbasic Window) 3. Type in: update YOUR_TABLE set obj=CreatePoint(CentroidX(obj),CentroidY(obj)) where YOUR_TABLE is the name of your mapinfo tabl

RE: MI creating points from centroids

Sidney Another alternative to Will's suggestion is to make a copy of the table (called say "My_New_Table") and issue the following command in the mapbasic window Update My_New_Table set object = createpoint(centroidx(obj),centroidy(obj)) This bypasses the need to store the x/y (lat/Long) values

Try this, Add a column called LAT and one called LONG to your table under table>maintenance>table structure (set them to type of float). Update the LAT column with Centroid(y), and the LONG column with centroid(x). Export a copy of that table as delimited text. Open the text file, and create p

RE: MI creating points from centroids

Hi Sidney It's pretty simple actually - just a few steps. 1) Make a copy of your original table - use File | Save Copy As 2) Close the original and open the copy 3) Use the Table | Maintenance | Table Structure command to add two columns to your new table - call them X and Y and set the type to

MI projecting on the fly

It was my understanding that vector coverages in different projections can be mixed willy-nilly, technically speaking, within a map window, and each would be reprojected on-the-fly to that windows projection as defined by the raster base projection. In a discussion with technical support at a com

I would use Update Column from the Table menu. MI allows you to take data from "hidden" fields and transfer it to viewable columns. These are the same data fields that report the area of a region when you double click on it. I needed to update my parcel table so I went ahead and did this. Below

Hi J-F! You can use this function in the Update Column dialog: ObjectGeography(obj, 7)---> same as ObjectGeography(obj, OBJ_GEO_TEXTANGLE) in MapBasic. Hope this help! Ciao!! ___ ||// François Bergeron || //Conseiller en Géomatique || //

Hi,   I had to import a .e00 file containing text objects. Many of them had an orientation. Now, I need to know this orientation so I can put it in a new field which will be used later for labeling purpose (in order to give the labels the same orientation as the text objects).   So, my ques
