For NEO B.V., I am developing a geo-information infrastructure (back-end, front-end) to support computer aided image interpretation and change detection (on aerial / satellite imagery). The platform facilitates:1. Centralized workload preparation and prioritization2. Expert reviewing and complex data-entry, red-lining, etc.3. Procedures and reporting of quality control (QC) and other management information4. Web dissemination of images and geo-information through generic mapping… Show more For NEO B.V., I am developing a geo-information infrastructure (back-end, front-end) to support computer aided image interpretation and change detection (on aerial / satellite imagery). The platform facilitates:1. Centralized workload preparation and prioritization2. Expert reviewing and complex data-entry, red-lining, etc.3. Procedures and reporting of quality control (QC) and other management information4. Web dissemination of images and geo-information through generic mapping services as well as tailored interactive mapping applications (portals)Specifically, the platform seeks to integrate manual workflows with automated processing. Unique selling point is the platforms' ability to synchronize information flows of parallel / converging processing steps. Recently, the platforms' data model has been further enhanced to handle time series analysis reliably and efficiently.NEO B.V. is using this platform on a daily basis, evaluating and monitoring real-world objects in the domains of civil engineering, public space, land use & cadastre and agriculture.Development and implementation is being done incrementally. Key technologyies:.NET/C#, PostgreSQL/PostGIS, Python, MapServer, GDAL, MapInfo/MapBasic, QGIS Show less

Availability of free (or affordable) medium-resolution satellite imagery (spectral and radar) is on the rise. CropMonitor is a platform for continuous monitoring of fields using time series satellite data of various sources/sensors, including Sentinel1/2, Landsat8, Modis and Aster. For the entire technology stack of web dissemination and service delivery (storage, back-end services and front-end applications) I am the lead developer.

For the entire technology stack of web dissemination and service delivery (storage, back-end services and front-end applications) I am the lead developer. Main goal is to offer targeted end users (farmers, crop advisors; non geo-information experts) an intuitive, responsive web application with maps, infographics and tabular information on objects of their interest, as well as alerts through parallel channels like SMS, email. Core technologies: PostgreSQL/PostGIS, UMN MapServer, PHP, JavaScript: VueJS, D3JS, OpenLayers, JQuery. CropMonitor is currently deployed in The Netherlands, Ukraine and Kenya Show less

The Netherlands Space Office (NSO) is a Dutch government agency promoting space technology, including the use of satellite imagery. Working with raw spaceborne imagery is not as easy as it may seem, therefore NEO B.V. has been contracted to download, process and georeference satellite image acquisitions. Subsequently, these images are made available through the interactive webmapping portal of Satellietbeeld targeting expert GIS users: http://www.satellietbeeld.nl (please notice: only available… Show more The Netherlands Space Office (NSO) is a Dutch government agency promoting space technology, including the use of satellite imagery.

Subsequently, these images are made available through the interactive webmapping portal of Satellietbeeld targeting expert GIS users: http://www.satellietbeeld.nl (please notice: only available for visitors from within The Netherlands). This portal is developed by me, full stack: from server-side catalog-driven map tile rendering services to client-side interactive mapping. For the front-end, a complete makeover is underway, improving user-friendliness and targeting a broader user group, including those visiting the portal using a mobile device.

LIANFOTO is a smartphone App (Android) aiming to replace the costly land surveying equipment and personel involved in updating the mapping of sub-surface infrastructures like water, gas, electricity and data networks. Using LIANFOTO, pictures are taken and both the position (GPS: lat/lon) and external orientation parameters (pitch, roll, yaw) are stored along with it. Subsequently, the acquired data is sent to the processing back-office (based on Agisoft) to build a 3D model; by dense-matching… Show more LIANFOTO is a smartphone App (Android) aiming to replace the costly land surveying equipment and personel involved in updating the mapping of sub-surface infrastructures like water, gas, electricity and data networks.

Subsequently, the acquired data is sent to the processing back-office (based on Agisoft) to build a 3D model; by dense-matching the images, the orientation parameters are enhanced and aligned. A orthorectified image can then be derived and used in CAD of GIS to track the as-laid position. In this proof-of-concept project, I was responsible for App development, as well as server-side image storage. Core technologies: Java (Android SDK, Android Studio), Python (server side) Show less

The core product I have been developing is ArcheoSuite: a platform for (geo)information processing in archaeological research. It has its use in the entire chain of fieldwork, analysis and reporting. ArcheoSuite allows for data collection using surveying equipment and mobile devices, both networked and offline. The collected information is directed into a common geospatial database, allowing for querying and (visual) exploration using GIS. Basically, specialists are continuously busy refining and augmenting the project dataset, based on their progressive understanding of the site.ArcheoSuite has grown to a mature medium-large software suite, developed by me--full stack: information analysis, architecture, coding. On average, about 15 people work with the software on a daily basis, greatly improving their productivity: repeated tasks have been automated and all sorts of integrity checks are constantly enforced on the data which the team is working on. Data management, data exchange and versioning between workstations / tablets is completely automated and workflows (like data entry and composing thematic maps) is supported by convenient tools.Core technologies: .NET/C#, MapInfo/MapBasic, Oracle Spatial, MS Access/VBA, some low-level bits and pieces in C/C++ Show less
