Question
1. Multifold Coverage For an 8-channel end spread reflection survey, draw a series of field layouts to help you answer the following questions 1). If one geophone is moved to the end after each survey, what is the maximum fold obtainable? Find out at least two CDP gathers with maximum fold number. Please mark the source and trace numbers. 2). If four geophones are moved to the end, is the fold number still the same? If not, what is the fold number? 2. Suppose that a 120-channel recording system is used in a seismic reflection survey with a 50-m geophone interval. What is the maximum multiplicity (fold) obtainable? If 15-fold coverage is desired, what's the shot interval? Graphically illustrate the two situations. 1:Explanation / Answer
ANSWER:
A simple way to lay out fields on content. Field layout is a light-weight, developer-friendly approach to theming which uses php arrays to define layouts, generating the necessary markup for complex node layouts automatically. If you are looking for an admin friendly solution with many more options and a user interface try Display Suite or Panels.
Field layout defines 9 default regions (top, float-left, float-right, body, bottom, etc.) into which node fields can be placed. To rearrange your fields, you simply implement a hook in your theme that returns an array specifying which region to put each field into. You override the layout for detail display, teasers, per-content type, per-view and per node-reference. Layouts can also be changed dynamically in your theme's node_preprocess hook to allow layouts to react to the node contents. Page level regions are also supported so you can place node fields outside of the main content region or in additionally defined blocks with minimal effort. You can also override the default field display formatter per context.
All rendering is done by drupal_render which brings some of the power of the Drupal 7 rendering model to Drupal 6, and provides a performance improvement over using CCKs 'exclude field' settings.
