Your project is great!!.I doing something similar but with the exception that I need to detect the the power off of the electric post with the help of a sensor and the shortest via to get there.I am very frendly with Jquery , mapserver,openlayer.But a friend of mine told me that QGIS is a great tool to genereate the map files but I have a question for you GisosDeveloper.¿How do you control that the way to get the hospital is a two way street?

@derek5457 thanks for appreciation. In this project, I did not consider the case of one way street but pgrouting has an option for handling one way streets.

QGIS has a plugin which also performs network analysis. Please see it as well.

@gisosdeveloper I'm very interested with ur project. Can u tell me how to make a relation between one program to another program? Or can u suggest me a tutorial how to build web GIS like this. Thanks before.

[gisosdeveloper]

@troycrasher If you are familiar with Web development then it would be easy for you to figure out how the whole thing is working. All the spatial data is stored in Postgres/PostGIS being served through MapServer (for background map) and directly for client side rendering. For map area, I used OpenLayers and for forms Dojo . If you need help regarding any of above steps, please feel free to ask me questions. For tutorials, I suggest you look at MapServer, OpenLayers websites.

@gisosdeveloper I'm still beginner with web development. Did you convert shp files before?

[gisosdeveloper]

@troycrasher What do you mean by converting shp files? If you mean how I have loaded shp file data into database, I have have converted shp file into database script with the help of shp2pgsql utility. Then I simply executed this script file. Remember, shp file will have an SRID (-1 if there is non) so before executing the script see if your shp file SRID exists in database.

@gisosdeveloper Could u send me a sample of code for this web GIS????

[troycrasher]

@gisosdeveloper Yes that's what I mean. Thanks.....

@gisosdeveloper Well I'm probably going to use Autocad Map. I know it can connect to postgresql. I'm doing this for myself in hopes to have some kind of website to show on my resume. I want something similar to what you have done where I can click on a parcel and see who the owner is and change the information from the browser. At my last company we used FileMaker and had Apple computers. I had a PC and autocad couldn't connect to a filemaker database.
