Hi there freelancer, I am looking for someone who is good with geospatial/mapping tools to determine the land area type (sometimes called toponym) for the city of Sydney, NSW, Australia based on a grid of approximately 5.6m and based on the colours used in google maps. Here are the detailed requirements and information: A. The information produced must be based on a "grid" down to the .00005 latlong level of detail (approx. 5.6 lineal metres). The "tiles" must line up exactly to this grid, so that the bottom left co-ordinate of any tile must be divisible by 0.00005 B. The information must be produced for every "tile" in Sydney - the area bounds can be obtained by typing in "Sydney" to google maps where it will show you the polygon of the city in red C. The information should be based on what either the majority of the tile represents (e.g. 40% blue (water), 60% pink (hospital) would be a "hospital" tile), or what is at the centre of the tile. I am fine with either method, whichever is easiest for you D. The output must be produced in CSV format with the following fields for each tile: 1. latitude (using the vertex at the bottom left or southwest corner of the tile) to six decimal places 2. longitude (using the vertex at the bottom left or southwest corner of the tile) to six decimal places 3. land type (using the logic in 2. above) E. The full list of land types you must identify is: 1. Land. Medium grey 2. Building. Light grey 3. Walking path 4. Road. White 5. Main road. Yellow 6. Highway. Orange 7. Tunnel. Orange outline / grey interior 8. Rail line. Grey hashed line 9. Water. Blue 10. Park 11. National park 12. Golf course. Dark green 13. Beach. Light yellow 14. Airport. Dark grey 15. Industrial complex. Grey 16. Educational facility. Light brown 17. Hospital. Pink The colour to the right of the land type is the colour coding which google maps uses for its PNG files. The attached image provides more information. An example of the output would be: -33.95045, 151.25690, beach As a suggestion for how to perform this task, you could use a tool such as ArcGIS or Global Mapper and do a raster conversion. Whatever method you choose should be systematic or programmatic, as I don't want a freelancer to spend any time manually performing this task. I really don't mind what method you use, as long as it quick, cheap and produces the above results. Please let me know if you have any questions, otherwise happy bidding!

I'm a GIS expert with more than 25 years of experience in the field. During the past 10 years, I've mastered many GIS tools including ArcGIS and Google Maps API. I've successfully finished 10s of GIS projects on freelancer.com (check my profile). About your project, I've some concerns: 1- Based on the area of Sydney and the grid resolution that you've specified, there will be about 5x10^18 tile which is a very huge number anyways. 2- Processing every tile requires accessing an online service (Google Maps) and making some raster analysis; therefore, it is not expected to be very fast. 1000 tiles per second is a very optimistic upper bound. 3- Given 1 and 2, the estimated time for processing all the tiles will be 5x10^10 days! 4- An important consideration is that you may be violating the terms of Google Maps license agreement. Consequently, I advice you to: 1- Consider using a coarser grid resolution 2- Consider using OSM instead of Google maps 3- Consider increasing the project budget at least to 1k USD Let me know if you have any questions.
