0a. FAQs
-
For some basic scanning strategies, as well as a description of resource scanning, check out the SCANsat wiki
-
What does SCANsat do?
- It allows you to scan planetary bodies for terrain, biome, and resource information and generate various kinds of maps.
- How does SCANsat affect gameplay?
- It allows you to see surface details from orbit from an interactive, zoom-able map. This will help you plan your missions (for example, landing near a divider between two or three biomes) and provide critical information you need to attempt a safe landing (for instance, the slope map will help you avoid treacherous hills)
- Will this version break my existing scans from older versions of SCANsat?
- No! This version is completely backwards compatible, and you current scanning state (which is stored in persistent.sfs) will be safe and sound. Nevertheless, you should make a backup copy of your game before upgading any mod.
- Do I need to attach a part to my vessel to use SCANsat?
- No, but.... You can view existing maps from any vessel, but you need to attach a scanner to add new data to the maps.
- What does the "field of view" mean?
- When a sensor is at or above its "best" altitude (but below its maximum altitude) the field of view is half of the width of the swath mapped by the instrument, if it were in orbit around Kerbin. In other words, a field of view of 5° would map swathes which are 1/36th (10°) of the planetary surface wide. The field of view is scaled for smaller bodies so that more of the surface is covered.
- What does the "best" altitude mean?
- At or above the best altitude, the sensor will operate with its listed field of view. Below this altitude the sensor suffers a linear penalty. A 10° FOV instrument with a best altitude of 500km would only have a 5° FOV at 250km.
- [Career Mode] Does SCANsat give us science points?
- Yes! For each type of map, if you scan at least 30% of the surface, you can transmit that Data for partial science points; up until the maximum value at 95% map coverage.
- [Career Mode] Is it integrated into the tech tree?
- Yes! This link tells you which nodes unlock which parts in the tech tree.
- [Contracts] Does SCANsat offer contracts to complete?
- Yes/No. Contracts are currently only supported through [third-party addons][6d].
- Can you add to SCANsat?
- Probably! First, check the issues page to see if it's already been requested. If not, add a new issue. Even better, attempt to add the feature yourself and submit a pull request. We'll catch the bugs for you!

2. Types of Scans
SCANsat supports several different kinds of scans (as opposed to scanning modules or parts).
- RadarLo: Basic, Low-Resolution RADAR Altimetry (b&w, limited zoom)
- RadarHi: Advanced, High-Resolution RADAR Altimetry (in color, unlimited zoom)
- Slope: Slope Data converted from RADAR data
- Biome: Biome Detection and Classification (in color, unlimited zoom)
- Anomaly: Anomaly Detection and Labeling
- Resource: Scan for chemical or mineral resource on the surface.
Other parts and add-ons are free to include one or more of these kinds of scans. In general, we would request that similar (same order of magnitude) scanning parameters and limitations are used on custom parts, but this is not a requirement.
2a. SCANsat Scans
SCANsat can scan for a few basic types of data. All of these (non-resource) scans are shown as indicators on the Small Map. For more information about basic SCANsat scanning checkout the wiki
- The Slope map is generated from either HI or LO data.
- The Biome scan only works for bodies that have biomes. For vanilla KSP, this means all planets except the sun and Jool.
- Anomalies are things the builds of KSC, hidden easter eggs, etc...
- The Anomaly data scans for anomalies from orbit, while
- BTDT shows a camera view of an anomaly once you are near it
- The Biome and Anomaly scans are combined into the multi-spectral scanner; indicated by MULTI
3. Resource Scanning
SCANsat will scan celestial bodies for resources using the new stock resource system. For a full description of both stack and SCANsat resource scanning methods check out the SCANsat wiki.
3a. Stock Scanning Mode
With default resource scanning options enabled the SCANsat resource map will automatically update as soon as a stock resource scan is completed.
No further resource scanning is necessary while using stock scanning mode.
3b. SCANsat Scanning Mode
There are two levels of SCANsat Scanning Mode:
- Disable Instant Scanning in the Resource Settings Window
- This will prevent SCANsat maps from being updated based on stock scanning coverage
- All stock scanning parts will continue to work as normal
- SCANsat resource scanning essentially works alongside stock scanning in this mode
- Disable Stock Scanning in the Resource Settings Window
- This will prevent all stock scanning functions
- All stock scanning modules will use replacement SCANsat modules
- These include:
- The planetary resource overlays (these are available in all scanning modes)
- The resource abundance readouts for the right-click menu
- The fixed-position resource map found on the Narrow-Band scanner
- This does not affect the stock biome scanning mechanic; resource abundance accuracy is still affected by biome scanning status, the same as with stock resource scanning
Resource scans are initiated in the same way as any other scan. In this case they use the stock M700 Orbital Survey Scanner.
Resource scanning proceeds the same way as standard SCANsat scanning instruments do. The grey scale color option generally works best when viewing resource overlays.
The resource system can be enabled through the SCANsat Big Map:
The M700 Orbital Survey Scanner provides a low-detail resource map for all available surface resources. For high detail maps a specific scanner is needed for each different resource. For stock Ore the M4435 Narrow-Band Scanner is used; high detail scanner modules are added to other parts for addon resources as needed.
The examples below show the difference between high (top) and low (bottom) resolution resource scans
Zoom map resource overlays require that a vessel with a narrow-band scanner be present in orbit and at an inclination high enough to cover the area in the zoom map.
If a vessel with a narrow-band scanner is not present, or its inclination is not high enough, the zoom map will not display the resource overlay. The same restrictions apply to overlay tooltips and the instrument window resource readout.
Resource overlays will work in IVA, too:
3c. Resource Settings
A number of options are available in the Resource Settings Menu for SCANsat resource scanning; this window has an in-game help function activated by selecting the ? icon in the top-right corner.
- Instant Resource Scan
- When this option is active all resources will be fully scanned for a given planet using the stock Orbital Survey Scanner instrument
- When disabled the SCANsat resource overlays will need to be generated using the method described above
- When Disable Stock Scanning is activated the Instant Scan option will automatically turn off
- Resource Biome Lock
- With this option active, biomes will need to be scanned from the surface to obtain accurate resource abundance reading on SCANsat maps
- When disabled all resource abundance values will be fully accurate, with no need for ground surveys
- Requires Narrow Band Scanner
- With this active the zoom map will only display resource overlays when a suitable Narrow-Band Scanner is in orbit around the planet, and its orbit covers the region showed in the zoom map
- Instruments Window resource readout will require a narrow-band scanner on the current vessel within its maximum altitude limits
- Planetary Overlay Tooltips will check for any suitable vessel in orbit around the planet before showing resource abundance
- When disabled the zoom map, instruments window, and overlay tooltips will display resource values regardless of Narrow-Band scanner status
- Disable Stock Scanning
- Disables the stock orbital survey
- Replaces the resource concentration readout from scanners with SCANsat modules
- Right-click menu resource concentration readout dependent on SCANsat scanning coverage
- Stock Scan Threshold
- Sets a threshold value for SCANsat M700 resource scans when stock scanning is disabled; can be disabled
- Once this value is reached a default, stock resource scan for that planet will be conducted
- Enter a new value, from 0-100 in the text box
- Reset SCANsat Resource Coverage
- This button will erase all resource scanning data for the current planet
- Regular SCANsat data will not be affected
- A confirmation window will appear upon clicking the button
- Reset Stock Resource Scanning
- Stock resource scanning data can be erased for each planet (does not affect resource biome scanning data)
- SCAN Planet Overlay Quality Settings
- Interpolation settings can be increased or decreased to increase the accuracy of overlays
- Overlay Map Size can be adjusted for higher quality, but slower maps
- Coverage Transparency adjusts the transparency of a grey overlay for areas that have been scanned but contain no resources, this makes it easier to track resource scanning progress
4. Basic Usage
Put scanner part on rocket, aim rocket at sky, launch. If your rocket is not pointing at the sky, you are probably not going to map today, because most sensors only work above 5 km.
You can start scanning by selecting a SCANsat part's context menu, enabling the part. Here, you will find a small map.
4a. FAQ: Finding a Good Altitude
Watch the data indicators on the small map to determine how well your scanners are performing. The right-click context menus also contain indicators for the proper scanning altitude.
too high
Solid ORANGE means you're too high (and therefore no data is being recorded):
too low
Flashing ORANGE/GREEN means you're too low (and therefore you have a FOV penalty):
just right
Solid GREEN means you're in an ideal orbit. Notice the larger swath width on the right:
4b. Mismatched Scanners
In these examples, the SAR and Multi sensors are not very well matched. Because the SAR sensors is ideal above 750km, and becuase it has a large field of view penalty if it's down near the ideal for Multi (250km), these sensors probably should not be used on the same scanner.
BIO and ANOM are ideal, but HI is not! | HI is ideal, but BIO and ANOM are off! ---|--- |
SAR (HI) has thin swaths due to low alt. | Multi and RADAR have similar ideal swaths --- | --- |
The mapping interface consists of a small-ish map of the planet, as far as it has been scanned in your current game. It scans and updates quickly and shows positions of the active vessel, as well as other scanning vessels in orbit around the same planet. Orbital information is also provided. For a slower but more detailed view, see the big map.
Note that the indicators flash blue when the gray-scale color option is selected on the big map.
Be sure to remember to pack enough batteries, radioisotope generators, and solar panels. If you forget, you'll run out of electricity, you'll stop recording data, and you'll see useless static:
Static! Oh no, adjust the rabbit ears!
4c. Biome Map
The Biome/Terrain button in the top right corner can be used to toggle between the standard terrain map and a biome map * When in biome mode, the current biome of each vessel will be displayed if it has been scanned
4d. Ground Track Indicators
When activated in the settings menu, ground track indicators are drawn for vessels around the current planet.
- The indicators are drawn only if at least one sensor on board the vessel is within scanning altitude
- The indicator width on the surface represents the scanning FOV at the equator
- The scanner with the widest FOV on a vessel is used to create the indicator
5. Big Map
A bigger map can be rendered on demand. Rendered maps are automatically saved to GameData/SCANsat/PluginData. Note that position indicators for vessels or anomalies are not visible on exported images (but they may be a future release).
You can mouse over the big map to see what sensors have data for the location, as well as terrain elevation, and other details.
Right-clicking on the big map shows a magnified view around the position where you clicked. Mouse operations work inside this magnified view just like they work outside, meaning the data displayed at the bottom window applies to your position inside the magnified view, and right-clicking inside it will increase magnification. This can be useful to find landing spots which won't kill your kerbals.
5a. Big Map Options
There are four drop-down menus along the top of the big map. These control, from left to right:
- The map projection type - Rectangular, KavrayskiyVII:, or Polar
- The map type - Altimetry, Slope, or Biome
- The resource to overlay on the map
- The planet to display
The icon in the center of the upper row regenerates the map.
The toggle icons along the left side of the map control the various overlays and the color mode.
The four buttons in the bottom-left open and close the other SCANsat windows.
The camera icon in the lower-right exports a copy of the map.
The re-size icon in the lower-right corner can be dragged to re-size the map.
6. Planetary Overlay
A separate window is used to control planetary overlay maps. These maps are drawn directly over the surface of the current planet; they use the same system as the stock resource overlays and will replace those maps if both are opened at the same time. Map coverage is dependent upon SCANsat data; only scanned areas will be displayed on the map.
6a. Terrain and Biome Overlays
SCANsat terrain maps can be displayed with the overlay window. These maps use the same height map data as the small SCANsat map and generate very quickly.
Tooltips can be activated to show data for the location under the current mouse position while in map mode.
SCANsat biome coverage can also be displayed using the overlay window.
6b. Overlay Control Window
Each available resource can be selected for the planetary overlay maps, along with biome maps and terrain maps. Biome maps are currently limited to the stock color scheme without borders.
