UAS-based Measurement of Crop Height and Biomass

Monitoring Crop Growth and Estimating Yield Production in Precision Farming
Monitoring crop growth provides timely and reliable spatial information to farmers and decision-makers employed in precision agriculture. The authors of this article tested the usability of UAS RGB images for estimating crop heights and biomass. The assessment was done at eight growth stages to provide timely and reliable spatial information.  Studying growth of crops throughout the growing season is a prerequisite for informed farming, decision-making and estimating yield production. Measuring the evolution of crop height and biomass during the growing season provides the essential indicators for growth and health and thus provides a means for dedicated irrigation, fertilisation and estimation...

Optimal GCPs with Onboard GPS

Block Adjustment for Photogrammetric Production of Map of Iran
The collection of Ground Control Points (GCP) for block adjustment is a costly and time-consuming operation. Onboard GPS enables a reduction in the number of GCPs without loss of accuracy. The authors tested configurations of GCPs when using onboard GPS for achieving optimal accuracy in production of an overall map of Iran. The use of GPS in photogrammetric mapping began almost from the inception of GPS technology. Initially, GPS was used to obtain the coordinates of GCPs. GPS saved time and labour as compared to conventional surveying methods, producing more reliable coordinates whilst reducing costs. In the next stage, GPS... (read more)

Instituto Geográfico Português Selects INPHO

Instituto Geográfico Português (IGP), the Portuguese Geographic Institute, have recently purchased a complete INPHO product suite for digital orthophoto production. The contract negotiations and system supply was done by GTBibérica S.L. (Spain), INPHO’s distributor in the Iberian and Latin American sales regions. The main task of the Portuguese Geographic Institute for the INPHO production line is producing full coverage of orthophoto maps for Mainland Portugal and generating high quality DTMs for some areas of the country. The UltraCamD digital aerial camera from Vexcel will be used for acquiring the digital aerial imagery. Under a protocol established with the Portuguese Forest... (read more)

LSO to Implement Mercator

Star Informatic (Belgium) has announced that the Land Survey Office (LSO) has chosen to implement Mercator in its cartographic production process. LSO is a central administrative body for surveying with nationwide competence, based in Prague, Czech Republic. LSO performs (among others) the maintenance of Fundamental Base of Geographic Data (ZABAGED) as well as the production of topographic maps in scales from 1:10,000 to 1:1,000,000. In choosing Mercator, LSO will optimise its prepress workflows, without compromising the beauty and accuracy of its maps. The MercatorPrepress design tool and the MercatorServer production engine will ensure not only quality and standardisation but also... (read more)

Shale Reservoir Characterisation

CGGVeritas has developed an integrated geophysical approach to characterising shale gas reservoirs, based on pre-stack azimuthal seismic data analysis calibrated with well log and core measurements to identify sweet spots. Relative production estimates across the reservoir may be derived by combining seismic estimates of lithological, geomechanical and stress properties, correlated to existing well measurements to predict porosity, volume of shale, carbonate content and water saturation. This technique has been applied to the CGGVeritas Tri-Parish multi-client survey in the Haynesville Shale with positive results. However, all shale plays are different, so the selection of geomechanical and lithological parameters that provide the... (read more)
