Aerial photography funding appeals
Aerial photography can be very useful for mapping purposes however it costs money. This page is a place where you can create an appeal for funds and monitor the success of the appeal.
There is no Yahoo Aerial Imagery of any detail available for the West Midlands. It is generally good enough to trace the outlines of parks and recreation grounds and the larger industrial buildings which have white reflective roofs. But even these traces are estimations.
The city centre has proved exceptionally troublesome to map given the low quality of GPS traces because of the preponderance of tall buildings. The recent NaPTAN import of bus-stop data has shown that our current alignment of streets in the city centre is not the best. Verification of NaPTAN data in the city centre and further improvement of alignment is not really possible without access to decent aerial photography.
This would enable us to correctly align streets, complete the NaPTAN verification and also improve and complete the mapping of major buildings.
Our current estimate of the cost is £5,000 for the area enclosed by the ring road.

Why can't we just use Google's photography?

How to raise the funds
- Say what you want and how much it will cost
- Say why it is important that you get it and what then beneifts would be if you got it
- Say who you have approached and what offers you have had
If you want to use commerical aerial photography you will need to raise money from organisations and individuals sympathetic with the project or who stand to gain in some way.
Transport authorities are often encouraged to support 'sustainable travel' including walking, cycling and public transport. Mapping showing walking routes is important and many, especially in the UK are frustrated with OS licensing costs, usage restrictions and their coverage of walking routes.
Some of the larger transport operators might be worth approaching to see if they would like to be associated with the project, particularly if there is a public transport emphasis on the project.
They may help as part of their 'Corporate and social responsibility' but might like their support to be recognised in some way in the local community
The project might fit with the aims of a charitable trust. See section on charitable partners below.
Individuals might be keen to help. You might consider accepting paypal donations and using a charitable partner for larger donations which can be tax deductable. It is probably not worth the effort of using a charitable partner for smaller amounts.
Managing the money
If you are raising money then you need to keep the money side very clear and well managed. It may be appropriate for the Foundation for fulfill this role, if not then another suitable organisation should be used.
Using a charitable partner
A charitable partner is relevant if you are planning to attract funding from a charitable trust or wish to reclaim tax from individual donations. This approach should be used in situations where a commercial approach would not be viable. The partner needs to have charitable aims that fit with the project aims and need to be comfortable with the project. The charitable partner accepts the funds from the donors and needs to ensure that the funds are used as intended. A charitable partner will normally take a small handling fee but this should not be a large percentage.
To date OpenStreetMap has used two charitable partners, including Campaign for Better Transport in the UK (only suitable for UK related work) and JumpStart who can work with projects in developing countries.
Hosting the data
Someone is going to need to host the map tiles and make it available.
more details needed.
Who owns the license
A legal entity is going to need to purchase the license. This might be the Foundation or some other suitable 'trusted' organisation. See 'Practical matters' for details.
How do people access the data
We are not able to give general public access to the aerial photography in most cases and the URL will normally be handed out on request to a group of people who will do the work.
