Data Services : LAS
Live Access Server (LAS)
Developed by: NOAA Pacific Marine Environmental Laboratory (PMEL), LAS info
LAS provides many options for producing high-quality maps and plots of gridded data.
- Our most capable interface for producing maps and plots of gridded time series, such as our forecast models.
- Wide variety of maps and plots possible, including depth profiles, Hovmöller diagrams, line plots, scatter plots, difference plots, and time series animations.
- Several options for customizing the plot style.
- Zoom into maps by drawing a selection box.
- Limited data download capabilities and output formats.
- No RESTful (URL-based) data download mechanism. Tip: Though an OPeNDAP service is provided (via F-TDS), we suggest that you use our primary TDS server for better metadata and other features.
- Some users may dislike the small font used in the plots, and text will occasionally overlap and become illegible.
- Coastlines are coarse in some areas and no basemaps are provided, such as satellite imagery, Google-like maps, or other geographic aids.
- Cannot drag/pan maps, click on them to query data, or double-click to zoom.
- For gridded data only. LAS does not support point data sets or our other non-gridded data.
- Includes all of our available forecast models and a few other gridded data sets like bathymetry.
- We have not yet included any satellite data.

- DODS binary (OPeNDAP)
- ASCII text table
- not viewable within interface; packaged with downloaded data as attributes.
- makes maps, time series plots, transects, depth profiles, and scatter plots
- zoomable maps and plots
- generates vector maps (wind, currents) from u (eastward) and v (northward) velocity components
- Produce animations of maps over time.
- Compare maps and produce difference plots between times, variables, or data sets.
- Apply rudimentary analyses to the plotted data: average, minimum, maximum, sum, or variance.
- Customize maps for viewing in Google Earth.
