Gi4DM (Geo-information for Disaster Management)      

Gi4DM (Geo-information for Disaster Management)
Antalya, Turkey, May 2011
By Prof. Orhan Altan, ISPRS President

Geomatics technologies are able to support management and recovery in the aftermath of manmade and natural disasters. However, disaster management also poses big challenges in all aspects of the geo-information cycle, from data acquisition, processing, management and delivery. For the seventh time, the International Symposium on Geo-information for Disaster Management (Gi4DM) brought in Antalya-Turkey, together researchers, developers, data providers and users from all over the world (155 participants from 33 countries) discussed these challenges.

By Jorge Abel Recio Recio

The ISPRS Hannover Workshop 2011 entitled "High-Resolution Earth Imaging for Geospatial Information" was hosted by the Institute of Photogrammetry and GeoInformation (IPI), Leibniz Universität Hannover, from 14th to 17th June 2011. The workshop was organized by the ISPRS working groups WG I/4, III/4, IV/2 and VII/2, supported by EuroSDR and the ISPRS working groups I/2, I/5, IV/3, and sponsored by Intergraph. The aim was to analyze the applications of the new sensors and virtual globes, and the automation of the processing chain of updating geospatial databases. During the conference 66 papers were submitted of which 38 papers and 4 invited papers were delivered in the oral sessions, and 27 posters were presented in the two dynamic poster sessions.

5th International Conference on 3D Geoinformation      

5th International Conference on 3D Geoinformation
Berlin, Germany, November 2010
By Gerhard König & Hartmut Lehmann

The 5th International Conference on 3D Geoinformation (3D GeoInfo 2010), held in Berlin, Germany from November 3-4, 2010 attracted about 175 participants from 21 different countries for two days of lifely discussion and debate. 3D GeoInfo 2010 provided a forum for international researchers from academia, industry and government in the field of 3D geoinformation to discuss all aspects of data collection and modelling, data management, data analysis, and visualisation.
The conference was jointly organised by the Institute of Geodesy and Geoinformation Science, Technische Universität Berlin, ISPRS Commission IV, Working Group 8, Open Geospatial Consortium, Inc. (OGC), European Spatial Data Research (EuroSDR), and the German Society for Photogrammetry, Remote Sensing and Geoinformation (DGPF).

Global Land Cover Mapping at fine resolutions

Dear friends,

Global land cover data are essential for global change studies and earth system simulation, such as the assessment of global environmental changes and the simulation of future environmental scenarios. In addition, land cover data are applied in national and sub-continental scale management, such as predicting and mitigating disasters, monitoring ecosystem health and services, protecting human health, and conserving biodiversity. Since 1990s, six global land cover datasets with spatial resolutions ranging from 300 meters to 1km were developed using coarse resolution remote sensing data (including MODIS, SPOT Vegetation). However, these global land cover datasets are inadequate to meet either the research needs of the global change science community or the operational requirements of national or sun-continent scale decisions and actions. The development of higher resolution global land cover dataset is becoming one of the top priorities of international and national earth observation programs.

Recently the Group on Erath Observation (GEO) has drafted its 2012-2015 WORK PLAN and invited official comments from its members. This four year's work plan reflects the conclusions of the GEO-VII Plenary, Beijing Declaration, and GEOSS Mid-Term Evaluation. It differs from the current 2009-2011 Work Plan in four main ways: (i) it derives directly from the GEOSS Strategic Targets; (ii) it groups Tasks into three thematic parts (rather than two as before); (iii) it features a streamlined number of Tasks; and (iv) it proposes an improved Work Plan management structure.. The major objective of the task is to 1) provide a suite of global land-cover and land-cover change datasets, based on improved and validated moderate resolution land-cover maps; 2) develop <50m global land-cover and land-cover change data sets, based on international community consensus and including a robust accuracy assessment; 3) improve the use of time-series products to characterize the nature and extent of land-cover change and dynamics.

This task is designed to reflect the national and regional initiatives for Global Land Cover Mapping at fine resolutions. China commenced a global land cover mapping project at 30 meter resolution at the beginning of 2010, led by State Bureau of Surveying and Mapping (SBSM). It is a three year project aiming to produce global land cover data sets for the year 2000 and 2010. Primary data sources include Landsat-class data and China's HJ data in combination with MODIS data as well as Chinese's weather satellite data. While the minimum mapping unit is 30m, the final products will include land cover types at 30m and the proportion of cover at the 250m level of spatial scale. USGS is preparing its 30 meter Global Land Cover projects for the initial establishment of baseline global land cover properties for the year 2010 coupled with a monitoring strategy that provides annual updates of land cover change. This Global Land Cover mapping at 30 meter resolution requires a tremendous amount of work and personnel face many difficulties in the different implementation phrases. SBSM and USGS will collaborate on combining their efforts for producing a global land cover database for monitoring land cover change. SBSM will focus on developing global categorical land cover classes, whereas USGS will focus on the percentage cover mapping for certain land cover classes. SBSM and USGS will also collaborate on methods and datasets of change detection and annual updating of the database. A federated Global Land Cover Information Portal will also be developed to publicize the 30-meter products and all other available global land cover data sets to the world. This concept has been supported by EC (JRC), FAO, GTOS (GOFC-GOLD) and many other institutes.

ISPRS is a GEO member and has been quite active in capacity building and other tasks. Global Land Cover Mapping at fine resolutions is one of the areas ISPRS has expertise and experience. I do hope more ISPRS working groups and experts will contribute to this GEO task.
