🗺 Topological maps are a simplified way to represent any subset of our the world. The simplification often implies losing part of scale, distance, area, form and direction. But we gain a very strong focus on what topology is all about: the connections between the features present on the map, and their relative positions to each other. 🇵🇹 In the example below, borders between the 24 contiguous Portuguese regions are highlighted. Those are the level 3 regions of Portuguese mainland NUTS (acronym from the french, Nomenclature des Unités Territoriales Statistiques). Since there is only one division in each of the two Portuguese Autonomous Regions of Açores and Madeira, they are not represented here. ⚡ Most often, topological maps represent linear networks, like subways or power grids, as that type of features is better understood without scale or accurate direction. Topological maps are also services from Digital Twins, designed for a better #TerritoryManagement, that you may ask for, whatever your business is. 📢 Could you easily identify each of the regions displayed? Which one are you from? Tell us in the comments, as we'd love to know. #Portugal #digitaltwins #4Dplus #map #topology #urbanplanning

Coastal hazards (e.g., #Coastal_flooding and #Coastal_erosion) are serious problems that both developed and #developing_countries suffer from. Such problems are being exacerbated because of the #ClimateChange and subsequent increase in #sea_level and more intense and frequent #storm_surges, besides the higher demand for #urbanization in #Coastal_cities for tourism and recreation purposes. Currently, I am on my way to Deltares to attend the #CoastalHazardsSymposium in #Delft, the Netherlands, as a representative of CES Consulting Engineers Salzgitter GmbH. The three-days Symposium celebrates the anniversary of the #XBeach model (15 years) and #SFINCS model (7.5 years), which are frequently used to predict coastal erosion and #flooding. On the last day of the Symposium, I am going to give a talk about one of my recent developments of #XBeach under the title "Does spatial variability of soil properties of a coastal barrier play a role in determining its breaching locations under extreme surges?". The abstract is attached.

Illustrating the changes in our forests over the past 20 years. Using analysis results from Landsat images with a spatial resolution of approximately 30 meters per pixel at the equator, the Global Forest Change dataset provides answers to '𝙬𝙝𝙚𝙧𝙚' and '𝙬𝙝𝙚𝙣' our forests have undergone changes. It also defines trees as vegetation taller than 5 meters. In Peninsular Malaysia, 2014 and 2016 recorded some of the largest forest loss areas, with totals of 2,909 km² and 2,903 km², respectively. #geospatial #remotesensing #environment #maps #datavisualisation We bring your geographic data to life with our comprehensive visualization services 🗺️ ✨ email us at [email protected] to find out more!

I am delighted to deliver my first talk, titled 'Trends and Status of Seagrass in Asia,' at an international workshop. There is a long way to go in addressing the challenges of mapping seagrass using remote sensing.Just received my certificate for this achievement!" #SeagrassMapping #RemoteSensing #YoungAsiaGeographer #ClimateChange #Linkedin

🌍 Exploring the Beauty of Geomatics and Measured Surveys 🌍 Geomatics and measured surveys have a unique way of taking us to some of the most beautiful places. Recently, our team had the incredible opportunity to conduct a comprehensive topographical and measured survey of a derelict care home overlooking the stunning Lake District. 🏞️ Breathtaking Views and Valuable Work 🏞️ The Lake District, with its serene lakes and picturesque landscapes, provided a truly inspiring backdrop for our work. Despite the challenges of surveying a derelict structure, the experience was enriching and rewarding. Our team meticulously captured every detail, ensuring accuracy and precision in our measurements. 📊 Why Geomatics Matters 📊 Measured surveys are essential for planning and development, helping to bring new life to neglected sites. By understanding the terrain and existing structures, we can contribute to projects that respect and enhance the natural beauty of these locations. 👷♂️ Our Team in Action 👷♀️ Here's a glimpse of our dedicated team in the Lake District, combining expertise with a passion for exploration. Their hard work not only ensures the success of our projects but also highlights the importance of preserving and appreciating the environments we work in. 🌟 Join Us on Our Journey 🌟 Follow our adventures in geomatics and discover how our surveys contribute to sustainable and informed development. Whether it's the Lake District or other remarkable locations, we're committed to excellence and exploration. #Geomatics #MeasuredSurveys #TopographicalSurvey #LakeDistrict #Surveying #SustainableDevelopment #Exploration #TeamWork #leica #leicageosystems #trimble #korec #Navvis #landsurveyor #measuredbuilding #revit #digitaltwin

Great to see our Convex Seascape Survey project mentioned in this interesting Forbes article. https://lnkd.in/eKHcWs8i

Itacimirim - Bahia - Brazil Another geospatial study developed in partnership with Coletivo Preserve Itacimirim. In this analysis, we used the vegetation index calculated from Sentinel-2 satellite surface reflectance data to extract information regarding vegetation suppression between 2020 and 2024. Another practical application of how the use of advanced technologies can be very useful in environmental monitoring. In green, we can see regions with high NDVI values, indicating the presence of vegetation, while red and yellow tones indicate negative or near-zero NDVI values, indicating the absence of vegetation. By comparing the maps from 2020 and 2024, we can easily identify areas of vegetation suppression. #remotesensing #orbitaldata #sentinel #environmentalmonitoring

Ever hear of Geocaching? It like a treasure hunt but instead of a map, you use your GPS. Here is a video of Hesperia's Historian, "Old Town Griz" explaining Geocaching.

MARITIME SPATIAL PLANNING IN THE NORTH AND BALTIC SEAS Planning the use of maritime space is very complex, involving a high number of interrelated interests, also among different sectors. The eMSP NBSR (Emerging ecosystem-based Maritime Spatial Planning topics in North and Baltic Seas Region) project brings together 15 neighbouring countries from the Baltic and North Sea Regions and fosters cooperation across the two sea basins for the efficient development of Maritime Spatial Plans. https://lnkd.in/dgV9-Uua

London Gatwick creates #geospatial platform for #buriedassets and #biodiversity London Gatwick has created a new geospatial platform using Esri’s #GIS (Geographic Information System) technology to support multiple operational areas at the airport, including #engineering and #environmental services. The system is already making engineering and construction works safer by reducing accidental strikes on buried utilities and enabling better management of the airport’s biodiversity. https://lnkd.in/e5xPNxrB
