Frequently Asked Questions

1. Are there any mouse and/or keyboard shortcuts?
2. How do I switch the map to satellite imagery?
3. Why do I get an "Error" from data cart sometimes?
4. Why do I see a time frame of 1985-2008 even though I didn't set one?
5. What is the current coverage of SciScope?
6. My search returned no results and SciScope has no suggestions. Why?
7. My search returned no results but SciScope has suggestions. Why?
8. Why do the data I downloaded has very few observations despite the fact that I used a fairly broad time frame?


1. Are there any mouse and/or keyboard shortcuts?
Zoom in     keyboard (+) or mouse scroll wheel (forward) or SciScope zoom control toolbar
Zoom out   keyboard (-) or mouse scroll wheel (backward) or SciScope zoom control toolbar
Deactivate   Right mouse button or "esc" to finalize polygon or deactivate feature browsing tool
Map type "A" for Aerial, "R" for Road, "H" for Hybrid


2. How do I switch the map to satellite imagery?
Map type can be changed using the VIEW menu on the upper right corner of the screen or using the shortcut keys. "A" for Aerial, "R" for Road, "H" for Hybrid


3. Why do I get an "Error" from data cart sometimes?
SciScope retrieves data from the original repositories over the Internet. Normally when data is ready "Processing" icon changes into "Download" icon. However since SciScope doesn't maintain copies of the data, any error on the data provider's site causes the request to fail, and presented to the user as an "Error".


4. Why do I see a time frame of 1985-2008 even though I didn't set one?
SciScope uses a default time frame if not provided by the user.


5. What is the current coverage of SciScope?
SciScope is currently in its early beta version. It provides access to observations from approximately 1.65 million sensors in the US adding up to 358 million observations.


6. My search returned no results and SciScope has no suggestions. Why?
SciScope runs on a knowledge base that contains information on how a given keyword relates to observations and abstract concepts. For SciScope to be able to process your query, it should first be able to recognize the keyword. If the keyword is recognized, SciScope will attempt to complete it as you type. If autocomplete doesn't recognize the keyword, it means SciScope won't be able to associate it with the underlying data and no results will be returned. To get results make sure that you use a keyword recognized by SciScope. In its current beta version SciScope supports several hundred keywords and their synonyms. This number will increase over time to provide more options and flexibility to the users.


7. My search returned no results but SciScope has suggestions. Why?
SciScope returning suggestions but no results indicate that there's no data for the selected time frame, area and keyword.


8. Why do the data I downloaded has very few observations despite the fact that I used a fairly broad time frame?
SciScope temporal search looks for any overlap in user-provided time frame and period of observation for a given observation site. Some sites are sample collection points rather than in-situ sensors thus offering sometimes no more than a single observation result. If the date of sample collection fall within your query time frame, it will be displayed in the results.
