eoMapper has a facelift

The eoMapper frontpage has a small facelift and we have added information on how to use the services for precision agriculture and creation of prescription files. During the three weeks the service has been up we have had visitors on the page from 130 cities or places distributed on all continents except Antarctica. As a tribute we display vegetetaion indices from all continents below. You can click on the images and follow the links if you log in to the site.

Forest analyses made easy -eoMapper

It is quite easy to make forest analyses with eoMapper, the online tool for precision cultivation, forestry and urban development.

Skärmavbild 2017-05-12 kl. 20.16.33

Go to www.eomapper.com  and create an account. This is necessary for us to save your processes for future use.Skärmavbild 2017-05-12 kl. 20.16.46

Select to start a new process, in this case change detection for clear cuts between 2016 and 2017.

Skärmavbild 2017-05-12 kl. 20.17.00

Draw a field boundary by clicking the vertexes and dubble klick to close the polygon. Do not make it to large as the processing time might be long.Skärmavbild 2017-05-12 kl. 20.34.15

Name the polygon as you please.

Skärmavbild 2017-05-12 kl. 20.34.26

Start the process and the available imagery over the area will be processed to identify areas that have been clear cut.

Skärmavbild 2017-05-12 kl. 20.17.17

If there are sufficient amount of available data the results of the change analyses will be displayed in red.

Skärmavbild 2017-05-12 kl. 20.17.40

Now yo can order the identified clear cut areas and download them as shape files or in geoJson format. The processes are also available by API.

Please contact Geografiska informationsbyrån if you have any questions, are interested in API access or have suggestions of improvements.

Precision farming made easy -eoMapper

It is quite easy to make analyses for farm management with eoMapper, the online tool for precision cultivation, forestry and urban development.

Skärmavbild 2017-05-12 kl. 20.16.33

Go to www.eomapper.com  and create an account. This is necessary for us to save your processes and field geometries for your future use.Skärmavbild 2017-05-12 kl. 20.16.46

Select to start a new process, in this case ‘Precision Farming’.

Skärmavbild 2017-05-13 kl. 17.00.52

Chose to draw a field boundary line, in Sweden there is the alternative to use agricultural block, i.e. LPIS geometries.

Skärmavbild 2017-05-13 kl. 17.03.08

Draw a field boundary, in this case half a quarter north of Presho in South Dakota, by clicking the vertexes so the line follows the field boundary and dubble klick to close the polygon.

Skärmavbild 2017-05-14 kl. 00.20.36

Name the polygon as you please, in this case Presho, but it could be your Farm name and a number. Press save.

Skärmavbild 2017-05-14 kl. 00.21.49.png

Start the process and the available imagery over the area will be analysed and cloud free images identified. The processes are made with Google Earth Engine and usually take under 1 minute to finalize. For the half quarter north of Presho there are five available images from April 1 2016 until now. At the moment only the latest scene is processed to a vegetation index (MSAVI2). Development to be able to chose between the images, to make time series analysis and for comparison between different years is on the way.

The vegetation index is shown with a brown to green legend showing bare land to lush vegetation. Use you local knowledge and decide which amount of Nitrogen that should be used per hectare dependent on the greenness of the vegetation. In this case the figures are filled for an extra spring nitrogen application. The greenest areas are considered to need less Nitrogen and more the lower the index become, the lowest index are considered to be to sparse and no fertilizer will be applied. This is hypothetical and local knowledge must be applied. Klick the next button to process the index to a Nitrogen load map.

Skärmavbild 2017-05-14 kl. 19.40.15

The proportion of Nitrogen in the fertilizer can be changed and the load will be adequately recalculated. Press order for prescription file alternatives.

Skärmavbild 2017-05-14 kl. 19.54.52

Press ‘Ladda ner’ to download the results in the preferred format.

Skärmavbild 2017-05-14 kl. 20.01.44

We will continuously add functionality to the service, focusing on the needs of grain farmers globally.

Please contact Geografiska informationsbyrån if you have any questions, are interested in API access or have suggestions of improvements.

Vegetationsindex för Golfbanor

Med eoMapper.com är det enkelt att ta fram information om hur grön en golfbana är. Det kan användas både för skötsel av gräsytorna, laddar man hem en styrfil i geoJson så ingår indexvärdena. Men kan vara intressant inför helgens rundor. Det har varit kallt i april och maj och banorna skiljer sig mycket mellan norr och söder. Gå in och kolla själv på eoMapper.com

Greenest pitch -check it out on eoMapper.com

eoMapper is developed for agtech purposes and use the power of Google Earth Engine to identify cloud free Sentinel-2 imagery globally, calculate vegetation indices and refine them to prescription files for fertilizers, pesticides or irrigation in combination with local knowledge of farmers.

Skärmavbild 2017-05-08 kl. 11.01.05

The vegetation indices could also be used to rank the pitches of the teams in the national football leagues in Europe.

#1 of the pitches investigated is Parc de Princes, home pitch of Paris Saint Germain

Skärmavbild 2017-05-09 kl. 19.24.33

Followed by #2 Estadio Santiago Bernabéu, home pitch of Real Madrid

Skärmavbild 2017-05-09 kl. 19.30.59

#3 Anfield is the home pitch of Liverpool FC

Skärmavbild 2017-05-09 kl. 20.11.06

#4 with just a glimpse through the ceiling is the Estádio do Dragão, home pitch of Porto

Skärmavbild 2017-05-09 kl. 19.52.45

#5 is Villa Park, home pitch of Aston Villa, with a significant shadow effect in the south east corner

Skärmavbild 2017-05-09 kl. 20.16.21

#6 Allianz arena, home pitch Bayern München has a semi artificial turf and hence a low vegetation index.

Skärmavbild 2017-05-09 kl. 19.42.23

#7 Stade Marcel Picot seems to be a semi artificial turf as well

Skärmavbild 2017-05-09 kl. 19.27.49

#8 Nya Parken, home pitch of IFK Norrköping is a artificial turf and has hence a vegetation index resembling bare land.

Skärmavbild 2017-05-09 kl. 23.14.11

If interested you can log in to eoMapper.com and check out your favorite teams home pitch. Hopefully there will be data available.

Innovativ informationsinhämtning med drönare och satellit

Geografiska informationsbyrån har beviljats stöd för att bild en innovationsgrupp med syfte att undersöka möjligheterna att ta fram en effektiv och tydlig process för informationsinhämtning om mark- och grödtillstånd i jordbruksmark med en kombination av industridrönare med högkvalitativa flygbildskameror och fria satellitdata från Copernicusprogrammet.

Stödet delas ut av Jordbruksverket och är en del av satsningar finansierade av Europeiska jordbruksfonden och avser innovationer inom området att återställa, bevara och främja ekosystem kopplade till jordbruk, trädgård och rennäring.
