Dear MnhnL Mdata User,
We want to continuously develop the Mdata service of the Natural History Museum Luxembourg and for this, we need your help. Please take a few minutes to tell us about yourself and how you use or would like to use Mdata or how we can improve it.

Coordinate Modifier for Excel Files
WGS84 (EPSG:4326) ⟷ GaussLux (EPSG:2169) ⟷ LUGRID-
WGS84 ⟶ GaussLux: Convert existing latitude and longitude columns into the corresponding GaussLux columns.
GaussLux ⟶ WGS84: Convert existing GaussLux columns into the corresponding latitude and longitude columns.
LUGRID ⟶ WGS84 and GaussLux: Convert an existing LUGRID column into the corresponding latitude, longitude and GaussLux columns.
Notes:
- No named columns will be deleted and newly created columns will be added to the end. However columns without header might be overwritten.
- Currently no support for formats other than .xlsx, and no support for documents with multiple sheets.
- Files must contain 2 columns with coordinates in WGS84 (EPSG:4326) (labelled "lat", "long" or similar) or in GaussLux (EPSG:2169) (labelled "x", "y" or similar) or just one column containing LUGRID coordinates (labelled "lugrid").
- WGS84 or GaussLux coordinates must not contain any characters other than numbers and optionally a decimal point
- When transforming LUGRID into another system, the resulting coordinates are the ones of the lower leftmost point of the square. The size of the square is additionally indicated in the grid_size column.
Modify your default settings
Here you can change the fields displayed in the observations search result table. In left box are all availaible fields.
In the right box are the current fields displayed in the result table.
To change a field, select it in the right box, select the new field in the left box an click the middle tripple arrow button. Click "Save" button to save your modifications.
The first result field 'date_end' cant be changed here but in the 'Search' menu under 'Result sort' option.

Number of Observations
Here you limit the number of observations that appears in the map and the result table. This limit isnt applied on the result download. The result download is limited to 200000 observations. Example: if the Num Observation filter is limited to 1000 observations you will see 1000 observations in the map and the result table. On the top of the result table you will see an info bar of the total of observations (this example 40339) and the number limited in map and result table (1000). You can download all 40339 observations in different formats.
Define Shape Filter
By default the "No shape" filter, which means no geographic filter, is applied. You can change this behavior be defining an other shape type.
You can choose from predefined shapes such as countries and "communes" from Luxembourg. The "Visible map" shape type means after searching only observations of the visible map area will be in the result set. The "Draw poygon" shape type means that you have to draw a polygon in the map. Move the mouse cursor in the map. The cursor will change to point. Mouse left button click define the first polygon point. Move to the next
polygon point and click on the left mouse button. And so on. Finish the polygon by double clicking on the left mouse button. The result will contains only those observations inside the polygon.
The boundary of the polygon should not crosses itself.
Example of a not accepted poylgon:
A search on such a polygon will fail.
