Re: MI Selecting Points and Polylines

[jchgis]

Dear Agustin: "Intersects" works very well with polylines. You may create a buffer around your points, and write something like:  Select * from MyBuffer, Polylines where obj Intersects Polylines..Obj into GonnaBeTransformed.     Also, polylines do so have centroids. Sincerely, Sonya JCH GeoInfo Agustin Estrada-Peña wrote: Dear List, I have two tables, one with points (some 30,000 records) and the other with polylines (some 260,000 records). They describe land-use patterns. I must to select the polylines surrounding points with a given attribute to convert them to regions (with MapLogix). How I can select these polylines? As polylines have no centroid, I can not use the "Contains" or "Within" clause? Every input is wellcome... Agustin ______________________________________ Prof. Agustin Estrada-Pena Dept. of Animal Pathology (Parasitology) University of Zaragoza (Spain)
