Yahoo! MapMixer + Quick User Guide

Yahoo! MapMixer + Quick User Guide

What is MapMixer? "The world is a big place. There are thousands of maps out there that provide unique details about any given destination. MapMixer is a new site that combines those maps with Yahoo! Maps to give you a better view of the world. It's easy to mix your own map. Upload an image of your map, use our layering tool to align it with Yahoo! Maps and we'll do the rest! Your map will have all the features of Yahoo! Maps (zooming, panning). You can also syndicate it on your own site or blog."

Quick user guide
Sign in to Yahoo.
Upload your jpeg,gif or bmp.
(no tif support at present.)

Yahoo Map Mixer Georeference Point
Two Points are needed to estimate the geographical position of the image.
Traditionally in a GIS environment this is at least 3 points.

*Top Tip - use the opacity setting

Yahoo MapMixer Georeferenced Opacity Setting
Use the control points on the edges of the image. Yahoo Mapmixer allows you to unpin your image which enables the moving of the yahoo map base


Yahoo MapMixer Georeferenced Rotate Image
Use the green circle to rotate the image - this helps to get an exact fit of the image.
*rotated image exaggerated here for example of the function.

Open Street Map - Maplexed

Open Street Map is Maplexed (Cartographic Text Placement Software)
Open Street Map Maplexed

OpenStreetMap (OSM) is a project aimed squarely at creating and providing free geographic data such as street maps to anyone who wants them. The project was started because most maps you think of as free actually have legal or technical restrictions on their use, holding back people from using them in creative, productive or unexpected ways.

Because the Ordnance Survey have the monopoly in th UK for Geographical Data and have crown copyright on all it's datasets. Good for standardisation of the data - data must be maintained at all scales across the UK. However the recent change in datasets. Landline being replaced by Mastermap and OSCAR replaced by ITN
(in this there is no link between these two datasets which for updating street maps is ridiculous).
There is one difference. Cost. It's expensive. Licencing is confusing and Ordnance Survey do not like any form of competetion.

So there now appears to be an alternative - Do it yourself (with a few helpers) with a GPS logger
The results are not perfect but they come close, close enough when free.

OSM was converted to Illustrator from a postgis database after
