What's New In Search (*** Please review. All headings updated on 1/31/17 ***)
As a complement to the dialog that shows the number of "not approved" and "not data checked" records you have,
we have color coded the "SurveyID" and "Crossing Code" columns in the search results (color blind friendly).
Orange colored Survey IDs indicate "not data checked," and "Fuchsia" crossing codes are "not approved."
We have added the Maine (2007-2015) data set to the NAACC website.
This data set uses the ME assessment protocol, and has all the functionality of the other data sets including
Excel reports, shapefile exports, photos and mapping.
We have changed the map symbol for the UMass Stream Continuity Project to a square. Since the "UMass" data set has
been scored using the NAACC scoring algorithm, the squares are colored with the same colors as the circles used to represent the
NAACC data on the map. Click the map information button for more detail.
We have added searching by NAACC Evaluation for the data sets that have this information (the NAACC and UMass data sets).
To compare the 'old' UMass protocol evaluation to the NAACC evaluation, export an Excel report for the UMass data set.
You may select the following combinations of data sets to search:
All data sets (excluding "Only Culvert Condition Assessments" if visible).
"The NAACC (after 6/1/2015)" data set and the "UMass Stream Continuity Project (2005-2016)" data set
Any single data set
Tip: Although you cannot select every possible combination of data sets, you
can return all the crossings from multiple data sets for a state. For example, to return all crossings from all data
sets for the state of Maine, choose all 5 data sets and select the state of ME under the "Location" heading.
This will return all the Maine crossings from the NAACC, and Maine (2007-2015) data sets.
Since the UMass Stream Continuity Project, Vermont and Connecticut data sets do not contain Maine crossing records,
they will simply be ignored.
If you click "Map Results," the map will show Maine crossings from the 2 data sets containing ME records.
General Search Help
"Dates" now default to "All" for all data sets, meaning all records will be returned
even if the date is missing for a record. To search by date, just click in the "Dates:" text boxes and use
the calendar or type in the dates. Only records having dates in that date range will be returned.
Clicking "Search" with the default parameters will always return all records for all data sets selected.
Set filters above to search for particular road/stream crossing records and then click 'Search'.
If you want to keep your search filter settings when you leave the search page, use the back button to return.
To reset your search filter settings, click the 'Search Crossings' link on any page.
Please note that there may be more than one Survey ID for a crossing location (i.e. xy style Crossing Code)
because the location may have been assessed by different teams at different times.
For all data sets, you may enter multiple "Survey IDs" at one time separated by commas without spaces.
For example - 122,20003,313,4004 or for the Connecticut(2004-2013) data set 001-001,001-002,001-003.
You may enter multiple "Crossing Codes" separated with commas without spaces - xy4242796572955280,xy4265055771254573,xy4264844271243666
The numbers in brackets in drop down menus represent the number of crossing locations assessed.
(Please note that the number of records returned for a search will likely be different than the number of crossing
locations assessed because there may be multiple surveys of a single location or because you do not have permission to
view some records.)
Although it is possible to map all the assessed crossings in all 6 data sets (about 58,0000 crossings), it takes a a couple of minutes,
and you may get messages saying that the page is "unresponsive" (click "wait" in this case). However, once the map renders,
it is very responsive when zooming or scrolling. Nevertheless, you may find mapping subsets of all 5 data sets (by state, town, watershed or dates)
to be more useful.
If you set the 'Location:' to be a state without a town, all unassessed crossings within that state will appear
along with your search results when you zoom in far enough. Since shapefiles are generated using the search results,
they will also contain unassessed crossings.
If you choose a town within a state, only the unassessed points within that town will appear along with your search results.
Otherwise, the map will show assessed and unassessed road/stream crossings that are within the smallest bounding box that contains
the assessed points returned by your search, but only if the number of unassessed points is less than 160,000 points.
The assessed and unassessed points outside this bounding box will not show on the map.
To display unassessed crossings for a town that has no () assessed crossings, select the town and click 'Search.'
You may need to zoom in quite closely to view unassessed points.
Unassessed points will not appear when displaying all crossing surveys for all states. Since we now cover
the 13 states of the North Atlantic Region, there are over 700,000 unassessed points, and it is not possible to display them all at once.
For a detailed explanation of the map functions and symbols, click 'Map information' in the map window.
The projection of all exported Shapefiles is WGS84, EPSG:4326.
