I'm trying to figure out how to do a similar thing with post codes, for the moment I've got a very basic mapnik style sheet that just produces town names, country borders and shaded postcode areas. http://maps.bigtincan.com/?z=7&ll=-33.52829,148.04077&layer=00B00FF OpenLayers can do semi-transparent layers over the top of a base layer, so I'll probably be going down that path too: http://sautter.com/map/?zoom=7&lat=-32.52829&lon=148.04077&layers=00B000TF ___ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk

I'm unsure about the technical details, but in general you would need a apache with mod_tile [0] / renderd / mapnik [1] to render your street-tiles with transparent background. Your Areal photos could (should?) be supplied by a WMS-Server (?) Both would be bundled together with OpenLayers [2]. As they also support vector drawings from external sources (GML, KML, etc.) I would suggest to put the field-outlines in here. Especially transparent street-tiles would be very cool to share to the community. If I'ts not possible to publish the tiles you may want to publish the styles-file & configurations you used to generate them to the wiki.

Interesting background and use case.

Yes. Absolutely. And provide it all as a web interface either with or without usernames and passwords. Many folks are doing similar things. Here is a site that will print a pdf map of a city for you with OSM data and an index. http://www.maposmatic.org/ You'll change a few things. You'll layer aerial images under the road info. You'll search on customer / field information rather than city names. And you'll only work in Kansas instead of France. ;-) Sounds like fun! > If this in not the correct group for this, then what group would I ask > this question?

This is not misuse! ;-) "... such as street maps..." is just one popular use. >From the front page of the wiki: "OpenStreetMap creates and provides free geographic data such as street maps to anyone who wants them. The project was started because most maps you think of as free actually have legal or technical restrictions on their use, holding back people from using them in creative, productive, or unexpected ways.

Does anybody know if they have > this data? Every EU country must have Land Parcel Identification System (LPIS). Almost all countries base it on orthophotos, which must be pretty accurate (RMSE <2.5 m) and no more than five years old. An example from Czech republic is good reading as an introduction http://www.lpis.cz/index_en.html. In short, very fine images exist, as well as very accurate data about actively used fieds. In most coutries neither images nor field parcel data are free but they can be used only for administrating and controlling farmer subsidies. ___ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk

One thing the UK is missing in rural areas are these. I guess the UK equivalent would be DEFRA? Does anybody know if they have this data?

I'm afraid I don't have an answer to your question. However you are not misusing OSM! We care about all geographic features, the name "OpenStreetMap" is has become a bit of a misnomer. I'm sure someone will be along soon with an answer to your actual question. Ciarán ___ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk
[OSM-talk] feasibility - different use of openstreetmap
Introduction: For my work we have a need for mapping "fields" agricultural sections of land for growing crops. We already put the legal description of the land in the our invoicing \ work order system and other information about the field, but we need a way to quickly print a high quality aerial photo of the section that the land is in and the outline of the field. I only need to cover 10 counties in central Kansas at least to start with, and I can get the free US Gov aerial photography and the field outlines from USDA. Question: Would it be possible/feasible to setup a map server like openstreetmap that shows all the street/roads along with my aerial photography and field outlines, and then make a search for the field by customer, by legal description or by field name? If this in not the correct group for this, then what group would I ask this question? I realize the your system is about street and I want to misuse it for land areas, but it is such a nice system and looks like a great framework to start building what I need from.
