DevMapTalya

How many square metres is a roof, a garden or a field? DevMapTalya is the free map tool of the DevAntalya community: you mark an area on the satellite picture and see its size, with sun, rain and elevation for that place. No account needed.

How it works

1. Find the place. Move the satellite picture, search for a place with the magnifier icon, or jump to where you are with the location button.
2. Add an area. The plus icon puts a square in the middle of the picture.
3. Make it fit. Drag each corner on its own. Tap a side to add a corner; the dot in the middle moves the whole area. The undo icon takes back the last corner or area you added.
4. Read the size. The bar at the bottom shows the size in square metres and dönüm while you shape. A press on it opens the climate of that place, the rainwater falling on the area per year, a rough solar estimate and the 7 day forecast.
5. Several areas. Add as many as you like with plus; their sizes are added up. When an area leaves the picture, a button at the top right takes you back to it.
6. Finish, or share. The tick icon or a tap on a free spot ends shaping; a tap on the area starts it again. The share icon gives you a link that contains your areas.

What you get

• Area in square metres, dönüm and hectares; the perimeter
• Elevation and the height difference inside the shape
• Average of the last five years: rain per year, rainy days, sunshine hours, solar radiation, warmest and coldest month
• Rainwater falling on the area per year, and a rough yield if it were fully covered with panels
• The 7 day forecast, sunrise and sunset

What you should know

• All results are estimates. The area is calculated from the corners you place by hand, and the satellite picture can be off by a few metres.
• Weather and climate values describe a grid cell several kilometres wide, not your exact plot.
• The results do not replace a survey, a land registry or cadastre entry, zoning information or an engineering calculation.

2. Privacy notice

This notice is given by the company above as data controller under Turkish Law No. 6698 on the Protection of Personal Data (KVKK).

2.1 Data we process

• Server logs: the web server records the IP address, date and time, requested path, HTTP status code and browser user agent of each request, for technical security and fault diagnosis. These logs are not used for marketing or profiling.
• What you send us: the name, contact details and message you provide when you write to us by email or WhatsApp.

The shape you draw is not sent to our server. It is kept in the part of the link after the "#" sign in the address bar, and browsers do not transmit that part to the server. If you share the link, the recipient sees the shape.

2.2 Outside services your browser connects to directly

The following requests leave your browser directly, not through our server. We neither see nor store what these services receive.

The servers of these services may be located outside Turkey. DevMapTalya does not connect to these services before you have agreed, with the button on this page or in the notice shown when the tool opens. If you do not want this transfer, please do not open the tool; reading this page alone does not contact them. The fact that you agreed is kept only in your browser and is not sent to us, so that the notice does not return on every visit (see 2.4).

2.3 Location feature

If you press "My location", your browser asks for your permission. Your position is used inside your browser only to move the map there; it is not sent to us and not stored. Because the map then shows that area, the matching picture tiles are requested from Mapbox or OpenStreetMap as described in 2.2.

2.4 Cookies and local storage

DevMapTalya sets no cookies. It keeps a single entry in your browser's local storage (localStorage): the date on which you agreed. This entry is not sent to us, is valid for twelve months at most, and only keeps the notice from returning on every visit. You can remove it with the "Withdraw agreement" link in the tool's details, or by clearing this site's data in your browser. Nothing else is stored.

2.5 Purposes and legal grounds

• Server logs: to keep the site secure and available, based on the legitimate interest of the controller (KVKK art. 5/2-f).
• Contact content: to answer your request (KVKK art. 5/2-c and art. 5/2-f).
• Connection to the outside services: based on the explicit consent you give by pressing the button when opening the tool (KVKK art. 5/1 and art. 9).

2.6 Transfers and retention

Your personal data is not sold, not shared for marketing and not passed to advertising networks. Legally authorised public authorities may receive information on request within the applicable legislation. Server logs are kept only as long as the technical security need requires. Correspondence is kept until the request is resolved and any statutory limitation period has passed, and is then deleted or anonymised.

2.7 Your rights (KVKK art. 11)

By applying to the data controller you may learn whether your personal data is processed, request information about it, learn the purpose of processing and whether it is used accordingly, know the third parties in Turkey or abroad to whom it is transferred, request correction of incomplete or incorrect data, request erasure or destruction under the conditions of KVKK art. 7 and the notification of these operations to third parties, object to an adverse result produced solely by automated analysis, and claim compensation for damage caused by unlawful processing.

Send your request in writing to the address above or by email to contact@tangelo.com.tr. Requests are answered within thirty days at the latest.

3. Terms of use

• Results are estimates. The area is calculated from a shape drawn by hand; weather, climate and elevation values describe grid cells several kilometres wide. The results do not replace a survey, a land registry or cadastre entry, zoning information or an engineering calculation, and must not be used as such.
• The solar estimate is rough. Tilt, direction, shade, panel type and layout are not considered. Take expert advice before an investment decision.
• No warranty. The tool is provided "as is". No warranty is given as to accuracy, uninterrupted availability or fitness for a particular purpose. To the extent permitted by applicable law, all risk arising from use lies with the user and the operator is not liable for indirect damage.
• Dependence on outside services. Satellite pictures, map and weather data come from services of third parties. They can slow down, be limited or stop without notice.
• Fair use. Do not use the tool for automated bulk queries or to download map tiles in bulk.
• Governing law. These terms are governed by the law of the Republic of Turkey. The English and German texts are provided for convenience; the Turkish text prevails.
