The answer is not as simple as the question may imply. If we had one "best one" we would not need the others, we would just use the best. Horses for courses though, needs matter. Saying that. This blog gives an excellent comparison of 90 m SRTM and 30m ASTER with some reasonable statistics. The winner is... well, actually you have no winner but 90m SRTM ...

The data is not available for free. The product is Strava Metro as you said (https://metro.strava.com/), and they sell the data. You cannot access other peoples tracks through the API without their permission.

You have some environnemntal data there, provided by le Muséum National d'Histoire Naturel. The data.gouv.fr portal just opened few days ago. IGN geoportal : http://www.geoportail.fr/ Some data from IGN are available for free. You will find many ressources regarding hydrology on that document (pdf) - see also http://www.eaufrance.fr. Regarding geology, BRGM ...

The OSM Wiki has instructions for downloading to different formats. And here is some information about shapefiles. Cloudmade has produced exports to different formats for France and can be found here.

One other approach is to use the Overpass javascript library to query the read-only OSM API. You can write a query that will select all of the relevant tags for an area. Here is an example from the wiki: <bbox-query s="51.15" n="51.35" w="7.0" e="7.3"/> <recurse type="node-way"/> <query type="way"> <item/> <has-kv k="highway" ...

Thats because it is a multipolygon. You can use Multipart to singlepart located in Vector --> Geometry Tools to split them.

These are a few of good options to start: The European Environmental Agency provides a Urban morphological zones, which gives polygons of urban areas across Europe defined by Corine land. You can download the data here You can also check out Global Administrative Areas (GADM) here which is is a spatial database of the location of the world's ...

The Urban Atlas data from the European Environment Agency should also be of use. It provides "land use and land cover data for Large Urban Zones with more than 100.000 inhabitants as defined by the Urban Audit". The Shapefiles can be downloaded from the above link. An example of the data is provided below:

I could be wrong but I think they are in Lambert system. Check out this tutorial as it explains conversions and it deals with caves in france, so i would think its what you are looking for http://takenfromhere.co.uk/coordinate-conversion/

Nowadays The most common CRS is EPSG 2154 also called RGF93 / Lambert-93 http://spatialreference.org/ref/epsg/2154/ . It's for covering entire metropolitan France (because we have some isles far away ;) ) For the cadastre, to have more precision, the France is divided in 9 zones (see the following link) The EPSG code follow the rule "Conique Conforme ...

As "@user two seven two three nine" says, it depends on what you are trying to do. For the geosciences, there are a number of relevant papers in "Elevation Models for Geoscience", Geological Society of London Special Publication 345. A direct comparison can be found in: Crippen RE, Global topographical exploration and analysis with the SRTM and ASTER ...

The european project Corine Land Cover gives you raster and vector data in different urban categories: 111 - Continuous urban fabric 112 - Discontinuous urban fabric 121 - Industrial or commercial units 122 - Road and rail networks and associated land 123 - Port areas 124 - Airports 131 - Mineral extraction sites 132 - Dump sites 133 - Construction sites ...

The forerunner of the current implementation of coordinate management in geodatabases was first integrated with the rest of the Esri product line (Arc/Info workstation, ArcView, and ArcIMS) when the "SDBE" product was purchased in the mid-1990s. At the time, the "SDE" training classes where half 'C' programming and half SQL, and multiple days were spent ...

IGN France has a good equivalent the Ordnance Survey MasterMap formally AddressPoint now Address Layer 2 database. http://www.ordnancesurvey.co.uk/business-and-government/products/address-layer-2.html based from many years of working very closely with OS addressing, it is in conjunction with Royal Mail (privatised in October 2013). Accuracy, it is ...

One way to investigate this sort of thing is to use the "Export" tab on a sample area on the main OSM site. If you export it as OSM XML, you will get a fairly large file, part of which will contain something like: -<node version="12" timestamp="2012-10-29T00:16:52Z" changeset="13668746" visible="true" uid="158826" user="cquest" lon="2.3549579" lat="48....

Do a Google image search on "free landmark icon". There are tons but whether you'll find all the ones you're after I don't know. Vector Stock seem to do a range but I can't say I've ever used them. Failing that, download Inkscape and make your own!

The OpenStreetMap’s French community are maintaining a rather exhaustive and accurate set of maps. Whether you’re a cartographer, a graphic designer or a developer, they’ve made it easy to reuse their work. As a matter of fact, from the OpenStreetMap’s OSM format, they’ve exported the maps to various formats such as Shapefiles, SVG, GeoJSON (to mention a few ...

This is the information available for polygon geometries for zipcodes in France, so I recommend you to check if your data is there. The dataset is available here. If you're using the georeferenciation as points, could you share the table or a couple of zipcodes which are not working? There are several possibilities here: Zipcode data is not recognized ...

The scale factor +k_0=0.999877341 is part of the lcc projection. I don't see where you applied that. The Jamaica lcc has +k_0=1, so no scaling there. This page has formulas for LCC 1SP and 2SP: http://www.remotesensing.org/geotiff/proj_list/lambert_conic_conformal_1sp.html For a reference, I suggest to use GDAL cs2cs for coordinate transformations.
