<html><body style="word-wrap: break-word; -webkit-nbsp-mode: space; -webkit-line-break: after-white-space; ">I want to use GRASS (and QGIS) for analysis of water well locations in a town. The basic data has been provided thru (ARCWare) shapefiles. While input of data to create the well location point maps is no problem, the shapefile format embeds the "real" spatial location data in a proprietary file (the .shx index files). So I can input shapefile data, including the dBase attributes, I can't get at the spatial locations; consequently I can't correct for any location errors made as a result of data input mistakes. Is there a way to access these shapefile index files using GRASS? Or is there a way I can use that fact that I can produce a GRASS location map of points to obtain (say a table of) (x,y) relative to some know location on the map? If I could solve this problem, I could probably move the whole well data set out of shapefiles and into more accessible database system, e.g. MySql.<div>thanks,</div><div>--dick peskin</div><div> <span class="Apple-style-span" style="border-collapse: separate; border-spacing: 0px 0px; color: rgb(0, 0, 0); font-family: Helvetica; font-size: 12px; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; text-align: auto; -khtml-text-decorations-in-effect: none; text-indent: 0px; -apple-text-size-adjust: auto; text-transform: none; orphans: 2; white-space: normal; widows: 2; word-spacing: 0px; "><div style="word-wrap: break-word; -khtml-nbsp-mode: space; -khtml-line-break: after-white-space; "><div style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; "><font class="Apple-style-span" color="#4A6BFB"><br class="khtml-block-placeholder"></font></div><div style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; "><font class="Apple-style-span" color="#4A6BFB"><br class="khtml-block-placeholder"></font></div><div style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; "><font class="Apple-style-span" color="#4A6BFB"><br class="khtml-block-placeholder"></font></div><div style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; "><font class="Apple-style-span" color="#4A6BFB"><br class="khtml-block-placeholder"></font></div><div style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; "><font class="Apple-style-span" color="#4A6BFB"><br class="khtml-block-placeholder"></font></div><div style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; "><font class="Apple-style-span" color="#4A6BFB"><span class="Apple-style-span" style="color: rgb(74, 107, 251); ">____________________________________</span></font></div><div style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; "><font class="Apple-style-span" color="#222084" size="3"><span class="Apple-style-span" style="font-size: 11px;; color: rgb(34, 32, 132); "><span class="Apple-style-span" style="color: rgb(34, 32, 132); font-size: 11px; ">Richard L.
