Heard Island: baseline data for monitoring longterm change. (f) 35mm photos (terrestrial) from fixed photo-points, 2003-2004.

Full description

The 35mm photos were taken by Dr Jenny Scott between December 2003 and February 2004 using two Nikon FM-2 SLR cameras with 50mm and 28mm lenses. The photos are part of a longterm fixed-point photo-monitoring project, started as part of ASAC Project 1181 (ASAC_1181), and the majority of image locations are the same as for the photo series taken by Scott between 1986-2000 (HI_VEG_PHOTOPOINTS_1). The photos serve as a baseline for documenting vegetation and landscape change, both between the two existing time series 1986-2000 and 2003-04, and in the future.

Area covered: eastern and southern Heard Island from Fairchild Beach (Compton Lagoon) to Long Beach.

Number of images: 1633, ranging between 1-3 MB. Images are stored in seven zip files, according to location. For more information, see metadata notes (word doc) accompanying the images.

Zip files cover the locations as follows:
- Fairchild Beach (FB). 181 images. Includes north side of Brown Lagoon.
- Skua Beach (SK). 313 images. Includes North Skua and Scarlet Hill.
- Stephenson Moraine (SP). 143 images.
- Spit North (SN) and SpitSouth (SS). 309 images.
- Paddick Valley (PV) and Winston Lagoon east (WE). 203 images.
- Capsize Beach (CB) and Winston Lagoon west (WL). 193 images.
- Long Beach, Lavett Bluff, Lambeth Bluff (LB). 291 images.

For each main location (ie each zip-file) there are folders with 28mm images (wide-angle) and folders with 50mm images (standard view) of basically the same series of photo-points. They are called eg. 'Skua 28mm', 'Skua 50mm'. The 28mm images can be viewed first to give an overall impression, and the 50mm images of selected sites can be viewed to give greater detail. The photo-points are arranged in approximate numerical order in each series of 28mm folders and 50mm folders. Note that the 28mm and 50mm series do not always match up completely; not all image series are repeated with 50mm and several images may be 50mm only. The majority of photo-points consist of a series of images (both 28mm and 50mm) forming a panorama progressing from left to right.

Photo-point location shapefiles:

There are two shapefiles showing location of DGPS photo-points and handheld GPS photo-points. The handheld GPS unit was used on several occasions when the DGPS system was unavailable. Image labels eg. JJS-SK-001 and JJS_SK_001 signify the same photo-point. For information on labelling, see metadata notes (word doc) accompanying the images.

Statement: The 35mm photos were taken by Dr Jenny Scott between December 2003 and February 2004 using two Nikon FM-2 SLR cameras with 50mm and 28mm lenses. The photos are part of a longterm fixed-point photo-monitoring project, started as part of ASAC Project 1181 (ASAC_1181), and the majority of image locations are the same as for the photo series taken by Scott between 1986-2000 (HI_VEG_PHOTOPOINTS_1). Each image is labelled individually and the ID label contains information on the photographer, location, ID number, position in panorama, lens, date, direction facing and whether the image is new or a re-take of an image from the 1986-2000 time series (HI_VEG_PHOTOPOINTS_1). For more information, see metadata notes (word doc) accompanying the images. Photo-point location shapefiles: There are two shapefiles showing location of DGPS photo-points and handheld GPS photo-points. The handheld GPS unit was used on several occasions when the DGPS system was unavailable. Image labels eg. JJS-SK-001 and JJS_SK_001 signify the same photo-point. Differences between 1986-2000 and 2003-2004 image series The basic ID of equivalent images in the 2003-2004 time series and the 1986-2000 time series is the same (eg. JJS-SK-001 or JJS_SK_001). Differences between the two time series are as follows: - The 1986-2000 images are mostly single images, and the 2003-2004 images are mainly panoramas. These include, and extend beyond, the scene shown in the single 1986-2000 image, and were usually taken with both 50mm and 28mm lenses. - The 1986-1988 images were taken with an Olympus OM-1 SLR camera (50mm or 28mm lens) and the 2000-2004 images with a Nikon FM-2 SLR camera (both 50mm and 28mm lenses). The coverage of the Olympus and Nikon lenses are slightly different. - Not all images in the 1986-2000 series were re-taken in 2003-2004, and some additional photo-points were introduced in 2003-2004. This is indicated in the image ID, eg with the prefix 'SKnew'. ########### NEW INFO AS AT 2008-05-06########### Minor errors noted in labelling of photopoint images, 6 May 2008 (these are mostly relevant if user is wishing to compare the photopoint series in this metadata record with the series in 'HI_VEG_PHOTOPOINTS_1'). WINSTON LAGOON WEST Photopoints 'JJS_WL_021,022' and 'JJS_WL_022,023,051' refer to the same scene but are located 1-2m apart. For practical purposes they should be treated as the one point. Photopoint 'JJS_WL_027028' is named incorrectly. Correct name is: 'JJS_WL_026-028'. Photopoint 'JJS_WL_008009' is named incorrectly. Correct name is: 'JJS_WL_006-009'. CAPSIZE BEACH There are no images for Photopoint JJS_013,011 - this point should be ignored. The images are included in photopoint JJS_CB_010,004. The correct name for this photopoint is JJS_CB_010,011,013,004. Two additional photopoints need to be added to the data. They are located by hand-held GPS points. They are: JJS_CB_014,105 (53 deg 09 min 45.6 sec South, 73 deg 38 min 29.7 sec East) and JJS_CB_012 (53 deg 09 min 41.1 sec South, 73 deg 38 min 50.8 sec East). SKUA BEACH The photopoint 'JJS_SK_029_04_28' is named incorrectly. Correct name is: 'JJS_SK_027_04_28'. The photopoint 'JJS_SK_027_04_28' is named incorrectly. Correct name is: 'JJS_SK_029_04_28'. STEPHENSON LAGOON The photopoint 'JJS_SP_055d_04_50_S' is named incorrectly. Correct name: 'JJS_SP_055d_04_50_S SKnew8'. LONG BEACH The photopoint 'JJS_LB_029026_04_28' (a, b, c) is named incorrectly. Correct name: 'JJS_LB_026_04_28' (a, b, c).
