Experiments On Long-Term Geodetic Monitoring By Low-Cost Gnss Receivers And Gogps Positioning Engine, Daisuke Yoshida, Eugenio Realini, Stefano Caldera, Masayuki Uchida Feb 2018

Experiments On Long-Term Geodetic Monitoring By Low-Cost Gnss Receivers And Gogps Positioning Engine, Daisuke Yoshida, Eugenio Realini, Stefano Caldera, Masayuki Uchida

Free and Open Source Software for Geospatial (FOSS4G) Conference Proceedings

This paper describes experiments of GNSS-based monitoring by means of different models and brands of low-cost receivers. Single-frequency observations were processed by Open Source goGPS Positioning Engine, in relative positioning mode with respect to a virtual reference station and three physical permanent stations. The experiments were carried out in Osaka, Japan and the results here described cover a timespan of eight months. The daily solutions show standard deviations ranging from about 1mm to 1cm, mainly depending on the base station observations quality.


Research On Voyage Navigation S/W Development Architecture Using Open Source Base Gis Modules, Lee Junho, Kim Jiyoon Feb 2018

Research On Voyage Navigation S/W Development Architecture Using Open Source Base Gis Modules, Lee Junho, Kim Jiyoon

Free and Open Source Software for Geospatial (FOSS4G) Conference Proceedings

Recently, as the number of voyage accident is increasing, massive damage of human life and property is following depends on scale of accident. ECDIS is navigation equipment essential for safe sailing and clean marine environment. However, ECDIS S/W is relatively expensive, and ocean-related international organizations such as IMO and IHO are designing the programs mainly for medium and large ships. OPEN CPN, SeaClear are existing as product based on Open Source Project, however they are lack of functions to use in actual voyage. ECDIS development by making combination with modules based on open source could be an alternative to follow …


Development Of Opensource-Based Photogrammetric Uav System Using Smart Camera, Jinwoo Park, Hohyun Jung, Dongyoon Shin, Chuluong Choi Feb 2018

Development Of Opensource-Based Photogrammetric Uav System Using Smart Camera, Jinwoo Park, Hohyun Jung, Dongyoon Shin, Chuluong Choi

Free and Open Source Software for Geospatial (FOSS4G) Conference Proceedings

Normally, aero photography using UAV uses about 430MHz bandwidth RF (radio frequency) modem and navigates and remotely controls through the connection between UAV and ground control system. When using the exhausting method, it has communication range of 1-2km with frequent cross line and since wireless communication sends information using radio wave as a carrier, it has 10mW of signal strength limitation which gave restraints on life my distance communication. The purpose of research is to use communication technologies such as LTE (long-term evolution) of smart camera, Bluetooth, Wi-Fi and other communication modules and cameras that can transfer data to design …


House Number Interpolation For Route Planning Applications, Stefan Funke, Sabine Storandt Feb 2018

House Number Interpolation For Route Planning Applications, Stefan Funke, Sabine Storandt

Free and Open Source Software for Geospatial (FOSS4G) Conference Proceedings

Nowadays users expect door-to-door routing from a navigation system; for a given address including street name and house number this requires at least an approximate location on the routable part of the OSM data. Of course, eventually the goal is to have every single building mapped and tagged in OSM with its housenumber. For most regions this is still a pipe dream, though. Often, only a small subset of the buildings have been mapped, and even if mapped, quite frequently their housenumber is missing. In particular buildings mapped automatically from aerial imagery typically lack more detailed tags. And even though …


Urbansim2: Simulating The Connected Metropolis, Fletcher Foti, Paul Waddell Feb 2018

Urbansim2: Simulating The Connected Metropolis, Fletcher Foti, Paul Waddell

Free and Open Source Software for Geospatial (FOSS4G) Conference Proceedings

UrbanSim is an open source software platform for agent-based geospatial simulation, focusing on the spatial dynamics of urban development. Since its creation UrbanSim has been used in the official planning processes for at least a dozen regional governments which were used to help allocate billions of dollars in regional investments in transportation infrastructure. UrbanSim was first conceptualized in the late 1990’s and implemented using the Java programming language. The technology landscape for scientific computing changed dramatically after that, and by 2005 UrbanSim was converted to Python, making heavy use of Numpy to vectorize calculations. By 2014, it became clear that …


A New Gis Toolbox For Integrating Massive Heterogeneous Gis Data For Land Use Change Analysis, Birgit Laggner, Natascha Orthen Feb 2018

A New Gis Toolbox For Integrating Massive Heterogeneous Gis Data For Land Use Change Analysis, Birgit Laggner, Natascha Orthen

Free and Open Source Software for Geospatial (FOSS4G) Conference Proceedings

Agricultural land use in Germany and related impacts on the environment and the use of natural resources are key research topics at the Thünen-Institute of Rural Studies. As spatial context is essential for the analysis of causal connections, GIS data regarding all necessary information was gathered during different research projects and prepared for processing in a database. In particular, the Integrated Administration and Control System, which was available for certain project purposes for several Federal Laender and years, serves as a very detailed data source for agricultural land use. We use different Open Source GIS software like PostgreSQL/ PostGIS, GRASS …


Osm - Gb: Using Open Source Geospatial Tools To Create Osm Web Services For Great Britain, Amir Pourabdollah Feb 2018

Osm - Gb: Using Open Source Geospatial Tools To Create Osm Web Services For Great Britain, Amir Pourabdollah

Free and Open Source Software for Geospatial (FOSS4G) Conference Proceedings

A use case of integrating a variety of open-source geospatial tools is presented in this paper to process and openly redeliver open data in open standards. Through a software engineering approach, we have focused on the potential usability of OpenStreetMap in authoritative and professional contexts in Great Britain. Our system comprises open source components from OSGeo projects, the Open Street Map (OSM) community and proprietary components. We present how the open data flows among those components and is delivered to the Web with open standards. Apart from the cost issues, utilizing the opensource tools has offered some distinct advantages compared …


A New Zealand Case Study - Open Source, Open Standards, Open Data, Brent Alexander Wood Feb 2018

A New Zealand Case Study - Open Source, Open Standards, Open Data, Brent Alexander Wood

Free and Open Source Software for Geospatial (FOSS4G) Conference Proceedings

The National Institute for Water and Atmospheric Research (NIWA) is New Zealand’s leading agency providing freshwater, ocean, climate, atmosphere and fisheries related research. Open Source software is widely used internally, both infrastructurally and in desktop systems. In 2011, the New Zealand Government passed “The Declaration on Open and Transparent Government”. This requires central government agencies to make taxpayer funded information freely available to the public, and encourages regional and local government, as well as agencies such as NIWA to comply. NIWA works closely with central and regional government, utilities, NGO’s and primary industry, making information discovery and delivery using common …
