Geoinformation ideas
At the university at the thesis, I was engaged in what I did some kind of analogue of Internet maps. The most interesting thing was working with cartographic information. When the cards in the network became more common, I was delighted, because You can do very, very interesting things. Having spent some time with the Yandex.Maps API, I realized that there was a tool.
The technical part of the idea.
Yandex.Maps allow you to put points, lines, polygons over maps. Calculate where to draw polygons, lines and points will help PostGis for PostgreSQL. It is mastered by PostGis quite easily. At least for the first result, it is enough to read the manual fluently.
The necessary information.
To make any calculations in PostGis, you must have a database of objects with their coordinates. At thesis, we took demo versions of MapInfo maps, parsed them and filled the base. Yandex.Maps support geocoding (and the opposite, too), but unfortunately it’s not possible to get the base of the city objects. In addition, not only the information about the coordinates of the objects is important, but also the description of these objects. A small nuance, the objects are not only buildings, but also roads, fields, forests, etc. Different information is on different resources. The same Yandex.Maps, Mapia, real estate portals.

A couple of ideas.
1) For real estate this may be an assessment of the attractiveness of housing. It is necessary to create a base of “positive” objects (shops, schools, kindergartens, hospitals, road junctions, parks) and “negative objects” (factories, factories, construction sites, busy roads, septic tanks, etc.). By constructing the polygons of influence of “positive” and “negative” objects, calculating the intersections of these polygons and the degree of their influence, we can derive some assessment of the attractiveness of housing.
2) It will be interesting for a business to conduct an analysis using the Voronoi diagram, as well as its varieties. A few years ago, I heard such a case. A customer ordered an analysis from a GIS company. The client had several shops in the city. In each store you could buy a certain product. Having built the Voronoi diagram, it is clear where it is better to put another store and where it is necessary to import more products.
3) A social project that suits government structures rather than business. Create a map with environmental information.
4) Comic idea . Put a point somewhere in the city. Set the zoom factor. Those. the point of each iteration is growing at 1km. This is done by means of building the buffer. Painting every new iteration you can get an interesting picture. Then you can indulge in two things: the method of increasing the area and speed.
