agricultural mapping Applications

  • Monoammonium Phosphate(MAP)

    MAP, with its low pH levels, is best used for high-alkaline soils. It is an ideal starter fertilizer because MAP contains less ammonia-nitrogen than DAP, reducing potential seed damage.MAP has been an important phosphate fertilizer for growers around the world for many years. It is completely water soluble, generally applied in the granular crystal form and used in the formulation of suspension fertilizers. As a granular material, it mixes well and frequently serves as an ingredient in bulk-blended fertilizers.

  • 3D ForestGIS with 3D Forest Inventory Data and Web Maps

    The 3D ForestGIS Application is a web based system with photogrammetrically processed 3D tree and tree models. You can use the System to precisely asess the wood volume, map the forest structure, include a variety of external geodata, query, print and share the maps with other Internet devices (PC, Laptop, Smartphone, Tablet). Test the system at http://3dgis.landconsult.de.

  • Fertilizers boosting soil productivity for agriculture sector

    The principle fertilisers used to boost soil productivity are phosphate based. Monoammonium Phosphate (MAP) and Diammonium phosphate (DAP) are used for their ability to deliver Nitrogen and Phosphorus (both macronutrients) to soil as solid fertilisers. Phosphate rock is the raw material for production and is extracted from large deposits across Florida, the Southern Mediterranean into the Middle East (namely Morocco and Saudi Arabia) and on into Russia and China. To this rock, sulfuric acid is added producing phosphoric acid. This acid is then reacted with ammonia and elemental sulfur producing a sulfur enhanced fertiliser. During this process, the dust produced can potentially reach explosive levels.

  • Rugged Mobile Technology for Forestry Management

    Forestry, by its very nature, takes workers into tough outdoor environments. We`ve had customers use our devices for timber cruising, GPS navigation, wildlife surveying and other types of forest management. From silviculture to wildfire management, the mapping, imaging and reporting capabilities of today’s rugged handhelds are an essential part of keeping our forests healthy — and forest workers efficient.

  • Aerial Surveys for Forestland Management

    Aerial surveys have become an integral part of forestland management, in large part replacing extensive field surveys. With current digital mapping capabilities, acquiring fast, accurate imagery is now not only essential, but also cost effective. Whether you need data for stand updating, depletion mapping or defoliation and damage assessment, you face the challenge of choosing the best technology and service for your investment.

    To accommodate your forestry business requirements, the GeoVantage approach makes easy and rapid collections of contiguous or scattered blocks possible, with coverage worldwide. GeoVantage offers a wide variety of digital ortho-mosaicked color infrared and natural color imagery from a quarter meter to two-meter pixel resolution.

  • Monitoring Tree Health Status

    Urban Trees are continuously exposed to several stress situations like air pollution, soil compaction, exhaust gases, damage of tree trunks, etc. For the responsible authorities it is important to anticipate these problems, as the consequences of possible accidents can be considerable (e.g. tree fall).EUROSENSE can provide a number of products that are important means for designing a correct policy for urban trees on short and long term.

    Acquisition of images -The acquisition of aerial or satellite images is the basis of tree inventory, mapping and most of our products. The assessment of the physiological tree status is done with colour infrared (IR) images. In the IR spectrum of the light, vegetation reflects much more and can hence be better analysed than in the case of normal light spectrum.

    Tree inventory - An inventory of the tree patrimony is the basis of a good tree management. Tree species identification, tree height, trunk circumference measurements and spatial localization of trees are primary needs for every Green City Service.
    Tree crown diameter - Based on semi-automatic aerial or satellite image analysis, the crown diameter of every tree can be calculated. The location, the extent of trees and their proximity to buildings can be visualised in a GIS (Geographic Information System) environment.
    Tree labelling
     - In the field, every tree can be labelled to assure the correct identification.

    Tree status assessment - Mechanical Status: EUROSENSE assesses tree stability with the Visual Tree Assessment method. This consists in identifying internal mechanical defects using external signs (e.g. appearance of the trunk, fungal fruiting bodies,…). 
    Physiological status: unhealthy trees, although appearing healthy on the field, can already exhibit obvious illness symptoms (lower red colour levels) on the colour infrared images. Mostly, this bad physiological status will only be visible on the field several years later.

    Data management - The integration of each tree into a GIS (Geographic Information System) database is essential. Within this GIS, the user can request, observe and add data during different stages of the tree management. By publishing the obtained data online, citizens can also visualize the results.

    Analysis tools - Trees can be evaluated through time by making evolution maps: improvement or deterioration of the health status of trees can be visualized. Statistical analysis, like tree species, health status distribution, etc. can be very useful in reports. Tree policy and management plan - A clear tree policy can result in a detailed management plan indicating concrete measures for every tree.
