I'm looking for an open source cloud GIS solution.
Current situation: Up to 100gb of data stored in file geodatabases that is updated daily. Data is used to create maps as well as geoprocessing tasks.
Ideally I only want one copy of the data however it needs to be shared across multiple companies working on the project who will also be adding new data and updating old. The GIS users are using ArcGIS Desktop v10.1 but for the rest of the project team I would like to have a data viewer that can do simple tasks such as measure and buffer. If we could create a few custom tools for the data viewer that would be great.
So my main criteria is Data storage:
- Store large volumes
- Good access from anywhere
- Quick and easy to update
- Manageable from custom front end?
- Easy to share data
- Secure
- Backed up
- Permission levels
Data viewer:
- Good symbology
- Transparency
- Good base mapping
- Deal with different projections
- Fast
- 2D and 3D?
- ID tool
- Link through to documents/images
- Add simple tools
- Zoom and measure
- View CAD and GIS, raster, vect, TIN
- Good access
- Create features
- Add in data and coords
- Permission levels
I am hoping to achieve a solution that is cost effective and well supported. I'm thinking it will be a bolt together solution made up of multiple components but I just don't know where to start.
There are better options than file geodatabases for storing the data which are better suited to multiple access but I can't remember what they are called (still an ESRI database)? Happy to use large database functionality attached onto them such as SQL or Oracle - would this help? I don't have ArcGIS Server only desktop which we'd like to remain using.... Surely open-source elements can still use ESRI desktop? I haven't had much joy with decent viewers either - the only two nice ones I have seen are Autodesks Infrastructure Modeller (Autodesk 360) and Google Earth Builder.... I know there is a price to pay for those two but if there is nothing open source that matches then I would be willing to pay. Apparently ArcGIS Online doesn't allow you to even interrogate raster images which would be no use to us as we deal with height data a lot. Hence this is probably going to be a miss match of all sorts of software but I'm sure I can get something working? I would also like a customised metadata editor rather than the nasty one in ArcCatalog... Something that would log the incoming data in a database and also apply that same metadata to the feature classes in the geodatabases automatically. I don't like producing lose XMLs like you get with shapefiles. Am I just setting unrealistic targets with pie in the sky dreaming or do you think something is achievable?
