geomapi 0.0.1

A standard library to manage geomatic data

GeomAPI

A joint API to standardize geomatic data storage and processing

Installation

Install it from here

Development

Testing the package is done in the tests folder with:

from context import geomapi

Docs

You can read the full API reference here: Documentation

Usage

The main use of this API is importing standardized RDF data into easy to use python classes. These python classes have a number of fuctions to analyse, edit and combine the most common types of data including:

• Images (pinhole or panoramic)
• Meshes
• Point clouds
• BIM models

Classes

This API provides a number of different classes to store data and its metadata.

Node

The parent class to interpret RDF formatted data, contains all the nescesary function to import and export RDF graphs.

Variables

self.name = None          # (string) name of the node
self.guid = None          # (string) guid of the node
self.sessionName = None   # (string) session node name
self.timestamp = None     # (string) e.g. 2020-04-11 12:00:01 UTC
self.sensor = None        # (string) sensor information P30, BLK, Hololens2, CANON, etc.

#Geometry
self.cartesianBounds=None     # (nparray [6x1]) [xMin,xMax,yMin,yMax,zMin,zMax]
self.accuracy = None          # (float) metric data accuracy e.g. 0.05m

#Coordinate system information
self.cartesianTransform=None  # (nparray [4x4]) 3D transform including location, scale and rotation 
self.geospatialTransform=None # (nparray [3x1]) ellipsoidal WGS84 coordinate system {latitude (+=East), longitude(+=North), altitude (+=Up)}
self.coordinateSystem = None  # (string) coordinate system i.e. Lambert72, Lambert2008, geospatial-wgs84, local + reference /offset

#paths
self.path = None # (string) relative path from the RDF graph to this node
self.graphPath= None # (string) absolute path to the folder with the RDF graph 

#metadata
self.graph = None # (Graph) rdflib
