I'm a computer scientist, currently doing a lot of work in the asset tracking field. I do plenty of application design, lots of programming and system administration for a living. I'm not a particular expert in a field but I do go deep into a subject/problem which is probably my only specialty ;-)

comment Openlayes - Loading 3 different KMLs via proxy; one appears and the others don't
pretty old question, but if you try the network link directly it will work. Your flightwise kml doesn't have 'Document' tag, which is needed for it to work on openlayers. Try the link inside flightwise instead. (but that one doesn't seem to work anymore now)

comment Different searching results in local Nominatim and openstreetmap.org
You're hitting the border problem when using extracts with geocoding. You'll have to (atleast I did) modify the code and get some polygon defined around the covered area. I've had this with the benelux subset once. I believe the shape files could also help you there.

Tx for bringing SpatiaLite to my attention, I use sqlite extensively, I didn't know it existed.

comment GPS Tracking by SMS
I'm using gammu-smsd with sqlite3 and it's been running for 4 years now using SIEMENS MC35i , any kind of terminal GSM modem speaking a decent protocol will probably work with it. This is a good suggestion. I also have to add it's running on ubuntu linux on a minimac.

comment Tracking a vehicle without GPS device
Not always. Chances are not every sat is being reflected, but if it is just a question of 10 vs 8 sats used to fix position, the results of 8 will not be so off it becomes an issue for road use. I don't even look at visible metrix, only sats used to determine a fix. You could even hang your GPS receiver upside down under your car using reflections. This is not theory, we've tested this a lot. But I agree with you it's that it's not optimal, you just need to ask the question, how accurate do I really need it...

comment slow import via osm2pgsql to postgresql database
If you built the executable, you can install it by doing a make install. The files you mention is source code and source headers which are used to build it and after that do not serve a purpose. After that, just use it like you used to do it, there should be no difference

I just checked your results on a mercator projection in Google earth, it's about 16 meters off. But it sure looks like it's more...

Any chance to see the geoJSON ? And do give us your openlayers versions please.

comment Nearest point on a line ( Spherical / Mercator projection )
That could indeed be the offset, like I said, I only use it on very small scale so the error margin must be really low using 8 digits. It's indeed just math, not geo-math :)

comment Nearest point on a line ( Spherical / Mercator projection )
That's about the scale I use it on, no more than that. I use it to see at what time a bus (public transport) passes a stop the closest. I am going to doublecheck it though and put it in a map to 'see' if it projects well on a sphere.
