City of Hamilton Orthomosaic 1999 & 2002

Description:

1999

This data resource consists of several hundred georeferenced orthoimages compressed and mosaicked as a set of 8 MrSID image mosaics. Aerial photography was flown in 1999. Pixel resolution is 12.5 cm. These mosaics were provided to the Library by the City of Hamilton in 2002. The City also provided an index to these images.

2002

This data resource consists of several hundred georeferenced orthoimages compressed and mosaicked as a set of 9 MrSID image mosaics. Aerial photography was flown in Spring 2002. Pixel resolution is 20 cm. An index is available for these images.

Spatial Reference and Data Type:

These images are available in UTM co-ordinates; horizontal datum is NAD83, UTM 6 degree Zone 17. These images are stored as MrSID image format with accompanying SDW world files. Other data formats can be accommodated, as the Geospatial Centre has access to a number of conversion utilities.

Data Access:

In order to access these mosaics, please visit the Geospatial Centre Reference Desk during regular reference hours, in Environmental Studies 1, Room 246. Library reference staff are available to provide further information about these data sets and to deliver data upon request. Under the terms of the Library's license agreement with the City of Hamilton, these data sets are for use by students, faculty, and staff at the University of Waterloo only.

Data Manipulation:

There are public workstations in the Geospatial Centre that provide access to GIS software, program extensions and data manipulation utilities. Patrons may use the GIS software in the library to view and manipulate the data. UW faculty, students and staff may copy these data to other media (Zip disk or CD-R) for use elsewhere.

Data Output:

ArcMap is able to export images as georeferenced TIFF extensions. Users may also choose to export images from MrSID Viewer as a Tiff or GeoTiff image. The mosaics may also be printed as a map view using one of the library's colour printers.

Use Restrictions/Licensing/Copyright:

This material is provided for academic, research, teaching, and personal use only. A data release agreement must be signed before the data is delivered. The City of Hamilton should be acknowledged on any derivative product, such as a map or an image.
