November 2017

GIM November 2017 issue

Object-based image analysis, UAS photogrammetry for mining, mobile mapping solutions, and effective use of geospatial big data – these are just a selection of the topics covered in the November 2017 issue of GIM International. Of course we also look back at Intergeo 2017, which was held in the last week of September. Additionally worth mentioning are two articles from Spain: one on the combination of UAS and Lidar in vegetation inspections, and the other on smart cadastral tools for real estate registration. Happy reading!

See below for the highlights of this month's issue.

Pioneers in Capturing Public Space

Interview Frank Pauli (CycloMedia)CycloMedia is a renowned mapping company specialised in large-scale and systematic visualisations of environments. Its headquarters are situated in The Netherlands, a country that is an excellent testing ground  for continuous innovation in mobile mapping solutions. GIM International's Wim van Wegen took to the highway and headed south to the old town of Zaltbommel and had a talk with Frank Pauli, CEO of the developer of advanced camera and image processing techniques.

OBIA and Point Clouds

Airborne laser platformsOBIA has been successfully applied for mapping land cover, forest and agricultural areas. Today, not only high-resolution multispectral images are available but increasingly also high-density 3D point clouds captured by airborne Lidar. Is OBIA also suited for the semi-automatic classification of Lidar point clouds? The author highlights promising prospects.

Low-Cost UAS Photogrammetry

UAS Photogrammetry for MiningUnmanned aerial survey (UAS) photogrammetry has proven to be a good alternative for capturing open-pit mines, but that too is expensive when done professionally. This article investigates whether low-cost UAS photogrammetry, using consumer-grade copters, is sufficiently accurate for 2D and 3D mapping of quarries.

Effective Use of Geospatial Big Data

Geospatial Big DataThe heart of any geospatial analysis system, regardless of its location or configuration, is increasingly becoming the server. All face a similar challenge, whether the system is in the ‘cloud’, a secure data centre or on a single machine running in an office. This challenge is primarily the ability to deal with the ever increasing quantities and variety of data the world now produces at an unprecedented rate. For mission critical systems, purposely designed software is required, tested in the most demanding environments. Try it cheaper and you waste money.
