About Resources

What is a Resource ?

A Resource in 3D Mapping Cloud, is a single unit of data.  That unit can be small or very large, and is of a certain type.  A resource can be best compared with a File on your desktop computer, but it can be more complex depending on the type.

In traditional Geodata, we talk about primitives such as Points, Lines, Areas.  These are valid types for a Resource.  Other types are GIS Image, such as an orthophoto, or WMS for a remotely accessed map.

Complex Resources

In 3D Mapping Cloud, a Resource can also be of very complex nature, such as a Mobile Mapping run, an Oblique Project, a UAV flight or an Indoor Floor.  These types of Resources are comprised out of multiple subsets, each representing a part of what is needed to work with this data. Typically, these resources contain data from different sensors (e.g. LiDAR scan data and Imagery).

For example, a Mobile Mapping run can contain a Point Cloud, many spherical and/or planar images, a trajectory file, a coverage, photo recording positions, envelope, legend preferences, and also a CRS identification (Co-ordinate Reference System).  However, the Resource appears as 1 entry in any listing, such as in the Console’s Catalog or Resources :

 

Uploading and Updating a Resource

3D Mapping Cloud expects the Resources to be valid and does not offer the tools to alter the Resources.  So it’s up to you to provide valid Resources, and we’ve built a great tool to help you do that.

Using Orbit GT’s upload tools, you are certain that all parts that are required for the Resource to be valid, will be uploaded.  The 3DM Content Manager checks the validity of the Resource before you upload it, saving a lot of time.  For example, Resources such as Mobile, Indoor, UAV or Oblique mapping are fully checked before upload can start.  Also, when you make a small change to a Resource, the upload tools will only upload those parts that have changed, for example, a single image, an orientation file, and so on.  This makes life very easy indeed !

Less complex Resource types such as vector data, a WFS, WMS or tiled map service, can all be set up using the 3DM Content Manager basic GIS tools.  It is advised for all Resources to convert them to Orbit native formats so we can guarantee performance.  Formats that have to be read entirely into memory, will cause the application to slow down (the whole file needs to be downloaded for every view) or even to crash if it would cause a memory overflow.  In order to get your hands on this, leant about 3DM Content Manager and it amazing capabilities.
