What is Atesmaps?

It is a 3D terrain viewer with avalanche cartography of the Pyrenees. It concentrates all the classified ATES zones, the most common avalanche trajectories and the evaluator trip planner, avalanche cartography of Institut Cartogràfic i Geològic de Catalunya and the layers of aspect, altitude and slopes. Track loading and 3d visualization allow you to plan the activity in the best possible way.



Avalanche Terrain Exposure Scale: Classifies terrain into three categories according avalanche exposure degree; simple, challenging and complex. ATES classification is based on physical terrain features and dynamic of terrain avalanches.

The Avalanche Danger Bulletin informs about the degree of avalanche danger and the possible condition of the snow cover for the hours after its emission. Its scope of analysis is regional and therefore does not adjust at the zone or slope level.

Avaluator Trip Planner uses the ATES classification scale. It helps the user to choose the objective of the exit combining ATES and Avalanche Bulletin, with three gradual levels of recommendation; caution, extra caution, not recommended.

The 3d visualization facilitates the interpretation of the terrain, to take references, to foresee points of decision making ... In addition, the selection of ranges of altitude, aspect and slopes and the superposition of avalanche cartography is incorporated.

How Atesmaps works?

At the time of preparing the activity, Avalanche Danger Bulletin, meteo, topographic map, reviews are consulted ... ATESMAPS focuses on concentrating all available cartographic information, based on such valuable information contained on ATES scale.

1. Select area

Click on an area on the viewer. Depending on the available cartographic information, the zones are classified into three categories, symbolized in a specific color. In the menu you can see what information contains each category.

2. Load tracks

You can load one or more tracks and manage them in the pop-up menu.

3. Activate 3d (in review phase)

The 3d viewer has an optimal performance for the computer. With a tablet or mobile, 2d vision is recommended.

4. Manage layers

Different layers are enabled: ATES and trajectories of avalanches common for the classified zones, ranges of aspect, altitude and slopes, and avalanche cartography of ICGC. The zones can contain one, two or three layers, depending on the available information. In the viewer menu, you can manage your visualization.

Terrain analysis scale

warning Prepare the activity optimally.

ATESMAPS incorporates cartographic and graphic information. Avlauator Trip Planner allows the user to choose the activity objectively, assuming the recommendations derived from the combination of ATES classification and Avalanche Bulletin. The bulletin, being a forecast of regional scope, does not allow to faithfully translate the forecast at slope level and therefore, it is the user who has to determine, recognizing the type of terrain and the snowy mantle, where the danger is. Thus, when we observe the mountain directly, we have to be able to analyze if the information contained in the Avalanche Bulletin and the trip Planner are adjusted to reality.

At the most precise scale, that of slope, the conditions of the mantle that we see and the analysis of the terrain that we carry out, are decisive in the decision making. The information of less detailed scales go to second term, since the hillsides can be affected by multiple variables that can not be assessed at a regional or mountain analysis scale.

Atesmaps Zones

At the moment, Pyrenees have 6 zones with ATES classification. Atesmaps concentrates 5 zones, except the valleys of Ransol and Sorteny in Andorra, which do not offer the information to be treated and incorporated into the viewer. On the other hand, from Atesmaps we have added aspect, altitude and slope layers allowing autonomous analysis of the user to transfer the information contained in the Avalanche Bulletin. Finally, the visualization of the avalanche cartography elaborated by the ICGC in the Catalan Pyrenees is offered.
