<HTML><BODY style="word-wrap: break-word; -khtml-nbsp-mode: space; -khtml-line-break: after-white-space; ">You can develop a site based on mapserver to get this done, and potentially use the ka-map interface which would let people pan and scroll around the map just like Google Maps.<DIV><BR class="khtml-block-placeholder"></DIV><DIV>But personally, given the limited programming background you described, I would recommend that you consider just using the Google Maps API (or Yahoo Maps, or MSN). All of them offer a fairly easy way for you to request a map that has a bunch of points labelled on it. You can use different icons for each point, so you might use colorcoded dots or balloon-like flags for the sightings, and use different colors depending on species, time, or other things.</DIV><DIV><BR class="khtml-block-placeholder"></DIV><DIV>The general gist of how to do this is that you write a program in a server-side scripting language like Ruby, PHP, Perl or Python. The program takes parameters that are submitted through a web form, uses those to make a database query, and then turns the results into HTML code that includes JavaScript which requests a map be drawn using the API provided by the maps vendor.</DIV><DIV><BR class="khtml-block-placeholder"></DIV><DIV>If you want the maps to be more sophisticated, for example letting you plot lines that connect several points, or filling in regions by color, or using many different types of markers, or tons of markers so that you would not want to draw them client-side -- these would all be arguments for you to develop your own server-side map component by starting with Mapserver and ka-map.</DIV><DIV><BR class="khtml-block-placeholder"></DIV><DIV>I hope this was helpful. For the record, I work for Vinq, a consulting company that has developed the free DataPlace.org site for Fannie Mae Foundation, working together with Placebase. We started with our own mapserver-based mapping engine, and wrote our own ka-map like javascript interface before ka-map was available, but we are in the process of converting to ka-map. We also ended up replacing mapserver with a combination of predrawn tiles using ESRI ARC engine, and overlays drawn using Mapnik, because of the higher quality cartography we were able to get. DataPlace displays demographic and other social science indicators from US Census, HMDA, IRS, and other data sets. Fannie Mae Foundation hopes to soon offer an API to DataPlace maps similar to the Google Maps API, but additionally letting users display maps with thematic overlays and showing data they have uploaded themselves.</DIV><DIV><BR class="khtml-block-placeholder"></DIV><DIV>I would be happy to answer questions about this individually as well.</DIV><DIV><BR class="khtml-block-placeholder"></DIV><DIV>--Mark Torrance</DIV><DIV><DIV><BR><DIV><DIV>On Oct 10, 2006, at 9:06 PM, Fred wrote:</DIV><BR class="Apple-interchange-newline"><BLOCKQUOTE type="cite">Hi all,<BR><BR>I'm a volunteer at a non-profit cryptozoology related website and we need some advise.
