SuperSurv 10.1 Supports Raster Formats and Online Maps

Supergeo’s SuperSurv 10 sets OpenStreetMap as its default online map. Due to the feedback, in SuperSurv 10.1, Google Maps will also be supported as base map, helping field surveyors complete their tasks more rapidly. SuperSurv 10.1 will be released at the end of November. In this version Google Maps and the image file format TIFF will be supported. Because TIFF is a widely-used format to store satellite images and digital elevation models, many field surveyors need to import TIFF images. There are more new features in SuperSurv 10.1. Snapping is one of the key functions newly added to this Android... (read more)

TatukGIS Releases GIS SDK for Java

TatukGIS has released the new Developer Kernel for Java edition, a general purpose GIS SDK for vector and raster manipulation, querying, and editing designed for application development using NetBeans, Eclipse, and other Java compatible development tools. As a native Java bytecode jar file, the Developer Kernel (DK) for Java is fully executable on Java Virtual Machine and truly multi-platform. Compiled applications have been successfully tested on Windows, macOS, Linux (Ubuntu x64), and Raspbian (Raspberry Pi). The DK for Java edition supports the same functionality and same extensive set of vector, image, and raster data formats, including database layer formats (via... (read more)

Standard to Improve the Way Information Is Referenced to the Earth

The Open Geospatial Consortium (OGC) has approved the Discrete Global Grid System (DGGS) as OGC Abstract Specification - Topic 21 [OGC 15-104r5]. The goal of DGGS is to enable rapid assembly of spatial data without the difficulties of working with projected coordinate reference systems. The OGC DGGS Abstract Specification standard defines the conceptual model and a set of rules for building highly efficient architectures for spatial data storage, integration and analytics. DGGSs represent the Earth as hierarchical sequences of equal area tessellations on the surface of the Earth, each with global coverage and with progressively finer spatial resolution. Individual observations... (read more)

Building an SDI with FOSS

A spatial data infrastructure (SDI) seeks to harmonise users with the provision of data, metadata, software and computational services to provide a productive and flexible environment for working with geospatial data. In an enterprise environment, the development of an SDI constitutes the foundations of the GIS department or group in your organisation. The Open Geospatial Consortium (OGC) provides a number of standards for various elements of an SDI. In this article, we will review the software options provided by the FOSSGIS (Free and Open Source software for Geographical Information Systems) community for developing an OGC standards compliant spatial data infrastructure...

Visibility Maps of Turin

Including Atmospheric Conditions in Viewshed Analysis of DSMs
High-rise buildings affect the skyline of a city and thus the human perception of urban spaces. From which points can a building, or parts of the building, be seen? The answer requires viewshed analysis of raster or vector 3D city models. Visibility is not just a geometric exercise in which lines of sight are calculated using standard GIS tools. Visibility and perception of space are also determined by atmospheric conditions, contrast between foregrounds and backgrounds including the sky, visual acuity and psychological aspects. Here, the authors present a simple but accurate method for generating visibility maps based on the above... (read more)

Global Mapper Adds Attribute Table Editor and Interactive Hillshade Rendering

Blue Marble Geographics has released Global Mapper version 19. Highlights of this release include an attribute editor; a tool for dynamically adjusting the light source position for hillshade rendering; and drag and drop docking functionality for improved multiview window management. Twenty years ago, Mike Childs began working on a project to create a simple data viewer for the U.S. Geological Survey. Little could he have envisaged that in the subsequent two decades, his pioneering work would lead to Global Mapper. The release of version 19 provides further evidence of the aggressive development philosophy that has driven the rapid growth of... (read more)

The Power of PostgreSQL and PostGIS - Interview with Paul Ramsey

In this article, we speak to Paul Ramsey about how both PostgreSQL and PostGIS can provide a solid foundation for any small to large organisational GIS architecture. Paul, a Solutions Engineer at Carto, has been working with geospatial software for over 15 years: consulting to government and industry; building a geospatial software company; and programming on open source software. He co-founded the PostGIS spatial database project in 2001 and is currently an active developer and member of the project steering committee. In 2008, Paul received the Sol Katz Award for achievement in open source geospatial software, and he speaks and... (read more)

GIS-based Cartographic Representation of Avalanche Forecasts

Annually, snow avalanches in Scotland are the cause of a significant loss of life. As a naturally occurring disaster they are unique in nature, usually being highly localised events, and often in remote areas. Their victims are often voluntarily at risk for recreation purposes and become the trigger of their own avalanche. Typically, avalanche prone areas are often those that recreationists most desire to use. Controlling access to these areas is ethically dubious and efforts to increase the safety of recreationists must therefore focus on educating and informing risk-based decision processes. Avalanche Forecasting Avalanche forecasting seeks to safeguard recreationists in... (read more)
