FIN Järvien vesikasvillisuusvyöhykettä kuvaava aineisto 1971 suomalaisesta järvivesimuodostumasta. Aineisto on polygonivektorimuodossa, jossa yksittäisen järven vesikasvivyöhyke esitetään moniosaisena polygonina. Vesikasvillisuusvyöhyke koostuu ilmakuvilta erottuvasta vedenpinnan yläpuolisesta (ilmaversoinen ja kelluslehtinen) ja aivan vedenpinnan tasolle yltävästä uposlehtisestä kasvillisuudesta. Vesikasvillisuusvyöhykkeen ja järven 0–3 metrin syvyysvyöhykkeen perusteella järville on laskettu kasvittumisaste-niminen tunnusluku, jota käytetään järvien ekologisen tilan arvioinnissa kuvaamaan rehevöitymisen aiheuttamaa kasvillisuuden runsastumista. Vesikasvillisuusvyöhyke on analysoitu Picterra-yrityksen koneoppimismalleilla Maanmittauslaitoksen hallinnoimista väri-infra- eli vääräväriortokuvista vuosilta 2012-2023. Vyöhykkeen analysointi on rajattu 1.7.–10.9. otettuihin ortokuviin. Lisäksi analysointi on rajattu seuraaviin vesienhoidon suunnittelun 3. suunnittelukaudella määritettyihin järvityyppeihin: • Pienet humusjärvet • Keskikokoiset humusjärvet • Runsashumuksiset järvet • Matalat humusjärvet • Matalat runsashumuksiset järvet Aineisto sisältää 698 järvivesimuodostumalta ilmakuvatulkinnan useammalta vuodelta. Havaittu kasvittumisaste on laskettu niille 977 järvivesimuodostumalle, joilta oli saatavissa tieto 0–3 metrin syvyysvyöhykkeestä. Aineistoon on jätetty järviä ilman syvyysaineistoa ja siten kasvittumisasteen laskentaa siinä tarkoituksessa, jotta aineistoa voidaan tarvittaessa hyödyntää muuhunkin kuin kasvittumisaste-muuttujaan perustuvaan tila-arviointiin. Aineistolle on tehty silmämääräinen tarkastus virheellisten havaintojen poistamiseksi. Aineisto voi silti sisältää väärintulkintoja. Kasvittumisasteen luontaisen vaihtelun mallintamisesta saadut tunnusluvut, kuten odotetut kasvittumisasteet ja kasvittumisasteeseen perustuva ekologinen tilaluokka, ovat ympäristöhallinnon asiantuntijoiden katseltavissa Pisara-järjestelmässä. Käyttötarkoitus: Ympäristöhallinnon tehtävien tueksi vesien tilan arviointiin. Järvien ekologisen tilan arviointia tekevät asiantuntijat käyttävät paikkatietoaineistoa ilmakuvatulkinnan laadun arvioimiseen yksittäisellä järvellä. Asiasanat: kaukokartoitus, ilmakuvat, vesikasvillisuus, seuranta, ekologinen tila Lisätietoja: https://geoportal.ymparisto.fi/meta/julkinen/dokumentit/Jarvien_vesikasvillisuusvyohykkeet.pdf https://vesi.fi/aineistopankki/koneoppimispohjaiseen-ilmakuvatulkintaan-perustuva-jarvien-vesikasvillisuuden-tilanarviointi/ ENG This data describes lake macrophyte zone on 1971 Finnish lake waterbodies. The spatial features are represented as multi-part polygons. The attributes are in Finnish. The zone represents emergent and floating-leaved vegetation plus submerged vegetation just above the surface of water. Together with lake bathymetric data, the percentage of vegetated littoral (PVL) was calculated. The PVL is applied in ecological status assessment. Lake macrophyte zone was detected from color-infrared aerial orthophotos administered by the National Land Survey of Finland. The detections were performed with the help of a custom machine learning model trained using Picterra. The detections were applied to orthophotos in 2012-2013 which were filmed between 1st of July and 10th of September. The detections were limited to humic and humic-rich lake waterbodies. There are detections from multiple years for 698 lake waterbodies. Observed PVL were calculated on 977 lake waterbodies which have bathymetric data to identify the 0 to 3 meters deep littoral zone. To potentially utilize the data for more than just the PVL-based approach, the data also have detections on waterbodies without bathymetric data and therefore observed PVL. A visual inspection of the data has been performed to remove erroneous detections. The data may still contain misinterpretations. Purpose of use: Support of environmental administration in ecological status assessment.

The 3D vectors for buildings are three-dimensional instances of the Building target category in the National Topographic Database (KMTK). The 3D vectors are produced with a high degree of automation from laser scanning data 5 p based on 2D vectors for buildings in KMTK. For the time being, data is available only from a few example areas, but the coverage will be extended to the whole of Finland as the laser scanning programme proceeds. The product belongs to the open data of the National Land Survey of Finland.

The Superficial deposits 1:20 000 / 1:50 000 data include material produced during the period 1972-2007 for land use planning, for the mapping and inventory of the natural resources as well as for environmental management and for scientific research. The main mapping scale has been 1:10 000. The data contains a sediment as a basal deposit at a depth of one metre. The minimum size of the basal deposit polygon is two hectares, with islands, mire and field enclosures, as well as geologically significant sites as an exception. The 0.4-0.9 m thick layers are described as overlying the basal deposit and, in geologically or economically significant cases, such layers could be even thicker. The minimum polygon size of the overlying deposit is usually four hectares. Thin covering layers under 0.4 m in thickness, which are difficult to delimit but effect an area of at least four hectares, are displayed as point data. Besides the deposits Quaternary geological formations formed in different ways, such as eskers and hummocky moraines, are described in the data. Other mapping sites such as small rock exposures, dunes and raised beaches are shown as point or line data. Coordinate reference system of the Superficial deposits 1:20 000 / 1:50 000 was transformed in March 2013. The transformation from Finnish National Grid Coordinate System (Kartastokoordinaattijärjestelmä, KKJ) Uniform Coordinate Frame to ETRS-TM35FIN projection was done by using the three-dimensional transformation in accordance with the recommendations for the public administration JHS154.

Seabed substrate 1:100 000 is one of the products produced in the EMODnet (European Marine Observation and Data network) Geology III EU project. Project provided seabed geological material from the European maritime areas. The EMODnet Geology III project (http://www.emodnet-geology.eu/) collects and harmonizes geological data from the European sea areas to support decision-making and sustainable marine spatial planning. The EMODnet Geology partnership has included 39 marine organizations from 30 countries. This data includes the EMODnet seabed substrate map at a scale of 1:100 000 from the Finnish marine areas. It is based on the data produced on a scale of 1:20 000 by the Geological Survey of Finland (GTK). The data has been harmonized and reclassified into five Folk substrate classes (clay + silt (mud), sandy clays, clayey sands, coarse sediments, mixed sediments) and bedrock. The data describes the seabed substrate from the uppermost 30 cm of the sediment column. The data have been generalized into a target scale (1:100 000). The smallest smallest cartographic unit within the data is 0.05 km2 (5 hectares). Further information about the EMODnet-Geology project III is available on the portal (http://www.emodnet-geology.eu/). Permission (AN17367) to publish the material was obtained from the Finnish Defence Office 29.9.2017.

The EMODnet (European Marine Observation and Data network) Geology project collects and harmonizes marine geological data from the European sea areas to support decision making and sustainable marine spatial planning. The partnership includes 39 marine organizations from 30 countries. The partners, mainly from the marine departments of the geological surveys of Europe (through the Association of European Geological Surveys-EuroGeoSurveys), have assembled marine geological information at various scales from all European sea areas (e.g. the White Sea, Baltic Sea, Barents Sea, the Iberian Coast, and the Mediterranean Sea within EU waters). This multiscale dataset includes EMODnet seabed substrate maps at a scale of 1:1 500, 1:5 000, 1:10 000, 1:15 000, 1:20 000, 1:25 000, 1:30 000, 1:45 000, 1: 50 000, 1:60 000, 1:70 000 from the European marine areas. Traditionally, European countries have conducted their marine geological surveys according to their own national standards and classified substrates on the grounds of their national classification schemes. These national classifications are harmonised into a shared EMODnet schema using Folk's sediment triangle with a hierarchy of 16, 7 and 5 substrate classes. The data describes the seabed substrate from the uppermost 30 cm of the sediment column. Further information about the EMODnet Geology project is available on the portal (http://www.emodnet-geology.eu/).

Potential cumulative impacts on benthic habitats is based on the same method than <a href="http://metadata.helcom.fi/geonetwork/srv/eng/catalog.search#/metadata/9477be37-94a9-4201-824a-f079bc27d097" target="_blank">Baltic Sea Impact Index</a>, but is focused on physical pressures and benthic habitats. The dataset was created based on separate analysis for potential cumulative impacts on only the benthic habitats, as these are particularly affected by physical pressures. In this case the evaluation was based on pressure layers representing <a href="http://metadata.helcom.fi/geonetwork/srv/eng/catalog.search#/metadata/ea0ef0fa-0517-40a9-866a-ce22b8948c88" target="_blank">physical loss</a> and <a href="http://metadata.helcom.fi/geonetwork/srv/eng/catalog.search#/metadata/05e325f3-bc30-44a0-8f0b-995464011c82" target="_blank">physical disturbance</a>, combined with information on the distribution of eight broad benthic habitat types and five habitat-forming species (<a href="http://metadata.helcom.fi/geonetwork/srv/eng/catalog.search#/metadata/363cb353-46da-43f4-9906-7324738fe2c3" target="_blank">Furcellaria lumbricalis</a>, <a href="http://metadata.helcom.fi/geonetwork/srv/eng/catalog.search#/metadata/f9cc7b2c-4080-4b19-8c38-cac87955cb91" target="_blank">Mytilus edulis</a>, <a href="http://metadata.helcom.fi/geonetwork/srv/eng/catalog.search#/metadata/264ed572-403c-43bd-9707-345de8b9503c" target="_blank"> Fucus sp.</a>, <a href="http://metadata.helcom.fi/geonetwork/srv/eng/catalog.search#/metadata/822ddece-d96a-4036-9ad8-c4b599776eca" target="_blank">Charophytes</a> and <a href="http://metadata.helcom.fi/geonetwork/srv/eng/catalog.search#/metadata/ca327bb1-d3cb-46c2-8316-f5f62f889090" target="_blank">Zostera marina</a>).
