I can't find any reliable info about some kind of "human" readable front end or api to pgRouting.
I have OSM PostGIS/pgRouting database which I would like to use to calculate paths between points. The problem is that I can't find any software that would use pgRouting to expose some ind of API. (WebService/comandline/anything usable)
I would like to provide to such API start, endpoint (GPS cords) and some parameters (don't use high ways and such). As a result I'm counting for distance, travel time and list of points to draw a poly on map.
Any ideas?
As I know, there isn't any apps, that you looking for, so you have to operate with direct SQL commands. (pgRouting is just a collection of functions in postgreSQL).
A simple pgRouting direction back-end API written in javascript nodejs express.
Easy to use and deploy.

The problem is to collect the map coordinates of some given locations and display on the site that i'm creating.I have heard that it is called Scraping.Can anyone tell me how to do this?
Google has really tight controls on what they let you get to -- there's an API, but there are limits on the order of 1,000 queries/day, depending on what information you need exactly. If you try to get around their API, they have incredibly clever algorithms that shut you out immediately -- attempting to scrape Google search results, I found that after a few minutes, they were able to immediately block me as soon as I hopped on new Tor endpoints.
The people at Google are extremely good software developers, and if they don't want you to have some info, you can't get it.
Can some one point me in the right direction.
I would like to create a C++ application that uses google maps.
I need to be able to do the following
Add markers.
Calculate distance between markers.
Work out long/lat from address.
Get address from long/lat.
Get address from mouse click on map.
I've seen some components that do this but they are abit pricy.
Not certain if this will help you, but Delphi & Google Maps API V3 is the first part of a multi part series on the same blog about using Google Maps API V3 in Delphi. Even if you don't know Delphi that well, you can see the names of components that are used.
Good luck.
Ended up using GMLib found at the following site

so far it has done everything i have needed.
I am looking for a geocoding service where I can make a request with an address or intersection, not necessarily separated into separate fields (street, city, state, etc.) and get the latitude and longitude, along with suggestions and corrections for misspelled or ambiguous queries.
I really like the Google Geocoding API, but the terms of use say that I am not allowed to store the responses or use the service for any purpose other than showing the result on one of their maps. I am planning to use it for a lightweight, mobile-friendly website that may have the option of displaying results with text only, so this would not work, assuming I am interpreting their terms correctly.
The Yahoo PlaceFinder API looks nice but it comes with similar restrictions.
I am trying to decide what would be a good choice. The Bing API looks good. I don't see any sort of restriction in their terms but am I missing something?
Does anyone know what would be a good choice? I have very limited funding, so I would prefer something that is free or cheap, at least for the near future.
You could try Nominatim, it's a tool to search OpenStreetMap data by name and address.
MapQuest provide a free API as long as you give the appropriate credit
I'm not sure how well it handles misspellings or ambiguous queries though!
I'm really hoping there's an existing service for something like this. I have a location (could be GPS coordinates or a street address, I can use geocoding or reverse geocoding services to switch between them) and I want to find a business that's listed as being approximately at that place.
If this service doesn't already exist, I'm thinking the best way to do what I want is to get a list of businesses close to a location, go through those and single out the closest one to the point I want, and say I'm "in" it if the distance is less than such and such.
If you have some pointers for which services I should look into (for either pinpointing one business or getting a list proximate to a location) or you think my methodology is stupid, please let me know!
edit: it's looking like the yahoo local search thing can pretty much do what I want. I'm going to start tinkering with that
Google Maps doesn't offer this yet. They do reverse geocoding from a lat/long to an address but not a business or interest.
I'm looking this up myself to see who offers this but the two I know of so far are GeoAPI (recently purchased by twitter) and SimpleGeo.
What you're looking for is Google Places which also allows you to specify the business type as well.
This is just a hunch, but have you checked out the Google Maps API?
I have a webapp from which I'd like to insert diagrams and images quickly and easily. I expect there is, somewhere out there, a webservice which will take a URL with a parameter that describes the vector graphics or diagram and returns an image.
No unlike what google charts does for graphing data.
Any resources or ideas on this?
If I had to build it myself, do you have some ideas of how I might accomplish that?
For instance, does PHP/asp/etc have a graphics library that's capable of rendering simple vector graphics?

Check out Raphael. Done by a bloke here in Australia.

Why not just use the Google Chart API?

Have you considered something like http://www.walterzorn.com/jsgraphics/jsgraphics_e.htm to produce actual vector graphics on the client side, instead of making requests to a server?
One possibility would be to generate SVG in realtime in the browser. This decreases browser compatibility, but that will decrease over time.
