NEW Interactive Rainfall Atlas of Hawaii

21 October 2011

The Rainfall Atlas of HawaiʻI Web site is a creation of the UH Manoa Department of Geography. It is a set of maps of the spatial patterns of rainfall for the major Hawaiian Islands. Maps are available for mean monthly and annual rainfall covering  the 30 year period 1978–2007.

The interactive map allows users to see the patterns of mean monthly and annual rainfall and corresponding uncertainty, zoom in on areas of particular interest, navigate to specific locations with the help of a choice of different base maps, and click on any location to get the mean annual rainfall and a graph and table of mean monthly rainfall. The locations of stations can also be shown on the interactive map. Clicking on a station gives both station and mapped estimates of monthly rainfall along with station metadata.

Rainfall maps can also be downloaded in various forms.

Rainfall measurements taken at over 1,000 stations were used as the principal source of information in the development of the rainfall maps. Files containing estimated mean monthly and annual rainfall and uncertainty for each station used in the analysis are available for download. A file with information on each station, including the name, observer, location, elevation, and period of record, is also available.

This is a fabulous resource for a wide variety of types of research. Check it out!

Re-opening of MAGIS lab and new Hawaii GIS data

9 September 2010

An exciting announcement About the UH Manoa Library’s Maps/GIS area:

Manoa MAGIS (Maps, Aerials & GIS) is pleased to announce the opening of  its new area in the ground floor of Hamilton Library.  Our maps are all in one place now and we now have a brand new MAGIS lab featuring 8 GIS  workstations.  The workstations feature ArcGIS, ENVI, MS-Office and Adobe Creative Suite.

Starting September 6, 2010, the lab will be open Monday to Thursday, 1-5 when school is in session.  All software is available with the exception of ArcGIS for 5 new computers which we expect to have installed by September 6.

For details on software support, please check out

http://magis.manoa.hawaii.edu/common/facilities.html

Anytime we have to retrieve maps or aerial photographs that are not available on our website, an appointment is strongly preferred. This also holds good for GIS data or a project which requires us to find the data in advance to incorporate into your GIS. We will work with you in person, on the phone or via e-mail as the case may be to service your request.

Download our brochure at:

http://magis.manoa.hawaii.edu/common/MAGISatUHMLibrary2010.pdf

*NEW GIS DATA*
To help us commemorate our new (old) area, we have put a new set of georeferenced maps on-line.  These are much sought after Historical Maps of Hawaii, 1885-1904. These can be viewed or downloaded here:

http://magis.manoa.hawaii.edu/gis/georeferenced

*NEW DIGITAL INITIATIVES*
MAGIS is trying something new with respect to receiving requests — we are recording initial requests online to keep track and to fine tune our services. Folks who want to access our Maps, Aerial Photographs, GIS, our MAGIS Lab, Large Format Services or request a Class Presentation can click on the appropriate link here:

http://magis.manoa.hawaii.edu/requests

Please remember that these online forms are an experiment to consolidate our requests so we can keep track off them and standardize our services.

Last but not least we are trying out a few other ways to increase our on-line presence and to publicize our services, MAGIS now has a blog! Please support it by checking it out at:

http://blog.hawaii.edu/magis

We are also on facebook, please friend us at http://bit.ly/magisfb

Best Wishes, Salim

Government Documents and Maps Open Again!

3 August 2010

It’s been almost six years since the 2004 flood and UH Manoa Library’s Government Documents and Maps (MAGIS) Department is finally open again on the ground floor of Hamilton Library, Room 6. Reference hours are 9:00 am-5:00 pm, Monday-Friday; closed Saturdays, Sundays, and holidays. You can now walk in to use the federal depository collection and the United Nations collection. Paging of documents has been discontinued. Patron-placed holds and recalls via Hawaii Voyager have been implemented.

It is strongly recommended that appointments be made ahead of time to use the maps from the Map Collection. The new GIS laboratory and classroom is being set up, and they anticipate GIS services to resume by the start of the fall semester. GIS services will continue to be available on an appointment basis.

To get to Government Documents and Maps, please use the open stairwell next to the Hamilton Library circulation counter. Persons with disabilities requiring the use of an elevator can ask staff at any service point for assistance.

For more information, call the department at 956-8230 or send email to govdocs@hawaii.edu or mapcoll@hawaii.edu

GIS Day – 4 November 2009

28 October 2009

Manoa MAGIS of the UH-Manoa Library is pleased to announce that we will be celebrating GIS (Geographic Information System) day for the first time ever on November 4, 2009. Under the auspices of the Library Forum we will host two speakers on GIS related topics.

Where: Room 301 of the Hamilton Library at the University of Hawaii at Manoa Campus.

When: 9.30 am and 11. am, refreshments at 9 am.

Details as as follows:

First Speaker, 9.30 am
Title: Role of Geographic Information Systems (GIS) in the Social Sciences—some applications.
Speaker: Shriram Bhutada, GIS Specialist, Extension Faculty, Center on the Family, University of Hawaii at Manoa.

There has been growing interest in application of GIS in social sciences recently. The intent of this presentation is to provide an introduction to the role of GIS in social sciences. GIS can play various roles in social science research such as geovisualization, spatiotemporal analysis, information integration and geographically weighted regression. Some examples of GIS projects will also be discussed. Additionally, the audience will be introduced to geocoding and custom geocoding programming along with a list of available GIS and non-GIS data sources.


Second Speaker, 11 am.
Title: Global Positioning System – GPS 101
Speaker: Karyn Nolan, President, Pacific GPS.

This presentation will give an overview of basic GPS principles including sources of error, GPS settings, accuracy requirements and differential correction (real time and post processed). We will focus on Trimble Mapping and GIS hardware and software and also discuss Geographical Information Systems (GIS) integration.

Refreshments are being sponsored by the American Society for Photogrammetry & Remote Sensing.

What: Fall 2009 GIS Essentials Class

When:
Track 1: Tuesdays: October 6, 13 and 20, 2009: 1 pm to 5 pm
Track 2: Thursdays: October 8, 15 and 22, 2009: 1 pm to 5 pm

More Digital Hawai Maps!

30 March 2009

Recently announced by our maps department:

MAGIS is pleased to announce that a set of Hawaii Historical Topographical Quadrangle Maps 1910-1933 is now online and available for download.  As far as we tell, these are not available elsewhere in a downloadable format.

http://magis.manoa.hawaii.edu/maps/digital/quads.html

-These are in 1:31,650 scale for all the islands except for Oahu which
is at 1:20,000 scale.
-These are downloadable as a geotiff, which means that it can be
imported into a Geographical Information System.  You may also simply
view the tiff as a jpeg with any image viewer.
-Maps for Oahu, Kahoolawe, Lanai and Niihau are forthcoming.

This project is truly a collaboration/partnership.  Many many thanks go to:

Henry Wolter at the United States Geological Survey who provided us with
the maps.
Ev Wingert of Geography and his colleagues who scanned the maps and
converted them into geotiffs.

The photographs are organized by county and then by island within each county. Coverage denotes the approximate area where the photograph lies within the USGS quadrangle (1:24,000) of the same name.

Most of the aerial photographs were taken by USGS and USDA, we also have a few flightlines and corresponding photographs from NOAA.

A jpeg version is available for free download.  However, should you need a high resolution image, please let us know.  All we need is the unique identifier located in the metadata section, next to the thumbnail view..
