Google Latitude

Thx to my good old friend Ed – Geospatial Technologist at Google – I’ve been looking into the functionalities of Google Latitude.

With this little app you can use your mobile to put yourself on the map and you can use this small map on your blog. Since I don’t have GPS on my mobile ( yet ), the poles of the GSM network are used to calculate the position. A little less accurate, but who cares.

Everyone can follow you now, if this is what you want that is questionable, but technically speaking it is nice of course.

AcClassify Enterprise

Classification-faseAcClassify – an AutoCAD Map utility from Autodesk Consulting – developed to leverage expertise around the AutoCAD Map drawing-structure saving this into migration-profiles.

Working with AcClassify distinguish the following fases:

Herewith we define features, how are they represented in the drawing and which specific requirements should they have to become such a feature.
for example the feature “building” consist of lineair objects with the layernamen = “B??_?

Herewith we connect the CAD-properties ( the input ) with the feature-properties in the database ( the output ), optionally “translating” for example colors into diameters.
AcClassify can create the schema-definition of the feature-tables in this fase, or an existing database-schema can be imported.

In this fase the current drawing will be migrated into the database.

There is also a command to migrate a complete folder of equal drawings with the same migration-profile.

CAD-data => AcClassify => GIS-data

CAD-data is in general structured according to a layer-model, where color, linetypes and blocknames can be used to make more difference.

GIS-data is in general structured according to a feature-model, where objects from the same kind resides in the same feature-table provided with their specific attributes.

what if John retires ... AcClassify – an AutoCAD Map utility from Autodesk Consulting – can filter CAD-data, based on various CAD-properties. AcClassify can “recognize” for example pipes of a certain type. After that AcClassify can migrate those CAD-entities into their corresponding GIS-features and optionally “tanslate” for example color-codes into diameters or linetypes into materials.

The major challenge encountered during this process is due to the lack of rigid attribute association with an AutoCAD DWG. AcClassify is designed to collect expertise around these DWG-entities to create a migration-schema which “maps” the unbound attributes to columns in a table, such as found in GIS database-tables.

AcClassify is a modular migration tool which is designed to work on a variety of input sources and output targets. It archives this by de-coupling the input and output phases from the classification engine with modules called adapters, configured in XML-config files.
